NEI Corporation Extends Its Advanced Materials Capabilities to Develop Fuel Cell Membranes


March 14, 2016

Somerset, New Jersey (USA) – NEI Corporation announced today that it has started developing polymer electrolyte membranes (PEMs) for fuel cells that avoid the use of perfluorosulfonic acid (PFSA) ionomers. PFSA materials, used in state- of-the-art PEM fuel cells, suffer from low proton conductivity at high operating temperatures, water management issues and carbon monoxide poisoning of the catalyst. The Phase I development effort, funded by the Department of Energy Small Business Innovative Research Program, is focused on producing a highly proton conducting heteropolyacid (HPA) based membrane. The new membrane incorporates heteropolyacids in an organic matrix in a way that has not been explored before, producing a unique structure that ensures that the active proton conducting species (HPA) is contained in a continuous interconnected channel. The goal is to develop a robust PEM that has high proton conductivity, low hydrogen and oxygen cross-over, and is highly durable for extended use in a fuel cell.

A fuel cell is a more efficient energy conversion device compared to traditional combustion methods. While a conventional combustion-based power plant generates electricity at efficiencies of about 35 – 40%, fuel cell systems can have efficiencies of up to 60%. Because they are energy-efficient, clean, and fuel-flexible, fuel cells have the potential to replace the internal combustion engine in vehicles and to provide power in stationary and portable applications. Fuel cell vehicle prototypes have been successfully introduced. Despite significant advances in fuel cell technology, there are still technical and economic obstacles in the commercialization of fuel cells. The US Department of Energy Roadmap calls for “accelerating the development of innovative technologies to enable a full range of efficient and clean advanced light-duty vehicles, as well as related energy infrastructure.”

Fuel_Cell_figure

NEI’s foray into fuel cells comes at the heels of creating a growing business in Advanced Materials & Services for the Lithium-ion (and the emerging Sodium-ion) Battery industry. NEI specializes in manufacturing and supplying specialty battery materials. The company supplies materials of compositions and powder morphologies that are difficult to produce and not readily available in the market. NEI also has an extensive battery research and characterization facility, which includes multi-channel cell testers that are utilized by customers. By providing custom-produced materials and tailored testing, developers are given new capabilities to enable next generation batteries.

The new program on fuel cell membranes also leverages NEI’s capabilities to create functionalized nanocomposite coatings. NEI’s NANOMYTE® line of protective coatings and surface treatments provide tailored functionalities, such as hydrophobicity, superhydrophobicity, oleophobicity, superoleophobicity, self-healing, fog resistance, self-cleaning (or easy-to-clean), scratch resistance, anti-corrosion, and anti-icing. In addition to imparting protective and aesthetic properties, NANOMYTE® coatings lead to gains in productivity and efficiency and therefore can be used in many applications that traditionally have not used paints or coatings. The coatings are versatile and can be applied on a variety of substrates – including glass, plastic, fiber-composite, metal, and ceramic.

Recent Advances in Self-Healing Fiber-Reinforced Composites (updated)

A New Nanotechnology Approach for Micro-crack Prevention and Impact Resistance in Self-healing Fiber-Reinforced Composites

Composites are rapidly becoming the material of choice for various applications. The more familiar carbon fiber composites are used where a lightweight structural material is required. Airplanes, such as the Boeing Dreamliner, utilize fiber composites for their high strength to weight ratio, which ultimately decreases fuel consumption. This also translates to the automotive industry; the lighter the car is, the more energy efficient it can be. Another example is sporting goods, such as lightweight bicycle frames, as they offer a competitive advantage in speed and transport. One can also find composites in newer materials for home decking, where longevity and durability to the outside elements allows these composites to last longer without the maintenance required for wooden decks.

While a composite might provide a major benefit over conventional materials, often they have a deficiency in different materials properties. For example, although fiber composites meet the requirements for strength as a structural material, they are susceptible to microcracking and impact damage due to the brittleness of the epoxy matrix. New material developments can overcome these challenges. For example, an introduction of nanoscale additives to the epoxy resin can provide self-healing and/or damage mitigation through toughening.

Making a Better Composite

Nanomaterials can be incorporated into composite materials in different ways. The nature of nanomaterials allows them to interact in ways not otherwise possible. This is due to the very small size of the nanomaterial, where such properties as strength and electrical/thermal conductivities can be improved in the resulting nanocomposite. We at NEI Corporation, an Advanced Materials Company, have utilized our expertise to design nanomaterials for making better composites.

Fiber Composites:

Improving the reliability, reparability, and reusability of fiber reinforced composites (FRCs) is a key aspect to advancing the current state of the art. The major problem with composites is the inherent brittleness of the epoxy matrix, which is prone to microcrack formation. If not prevented, the microcracks can lead to potentially catastrophic structural damage. NEI has taken on this challenge by developing several technologies to both mitigate damage, as well as repair any damage that may have occurred. These technologies, based on nanoscale materials and nanoscale structures, can be combined into one composite system to create a toughened composite material with self-healing capabilities (examples shown in Figure 1).

FRC_Fig.1

Figure 1: (Left) – Self-healing FRC composite fabricated as a panel; (Right) – Composite Overwrapped Pressure Vessel (COPV).

The self-healing technology enables the composite to heal microcracks through the use of a novel self-healing agent, which is combined with the epoxy matrix to form a microcrack prevention technology. The two technologies have been demonstrated for proof of concept in FRC structures consisting of flat panel carbon FRCs, as well as in carbon fiber composite overwrapped pressure vessels (COPVs). In the self-healing technology, a brief heat treatment is used to initiate the healing process. Self-healing can be repeated multiple times. When introducing new functions to the composite, the intent is to ensure that the original material’s properties are not compromised.

In one resin system containing a surface-modified nanoadditive, a significant increase in burst performance was observed after the COPV was cryo-impact-damaged and then self-healed. Initial cross-sectional analysis via microscopy showed good resin infiltration of the carbon fibers and no voids. Steps were taken to improve the mechanical properties of the COPVs by using a low-viscosity resin system that contained a different curing agent. This lower viscosity improved the processing of the COPVs, and results show that the burst pressure of these new vessels was 20 to 25% higher than the original.

Recently, we have developed a self-healing system that does not require thermal initiation. The system is a multi-scale, hybrid fiber system that incorporates multiple functionalities, including self-healing and increased strength and is compatible with FRC manufacturing. As such, it can be tailored to give specific properties of interest to the end-use applications of the customer. This approach utilizes core-sheath fibers, which comprise of a straw-like morphology in which a self-healing fluid is entrapped within a polymer straw (see Figure 2). When a crack forms and cuts through the sheath, the core fluid flows out and begins to fill the crack before finally curing.

FRC_Fig.2

Figure 2: (Left) – Schematic of a core-sheath fiber showing the straw-like morphology; (Right) – FRC coupon containing self-healing, core-sheath fibers.

Unlike single-target approaches, where one material property is often improved at the expense of another, robustness can be introduced to a COPV by a combination of a modified resin and nanoparticle additives. Unique nanoparticles are surface-functionalized to be compatible with the resin. Both organic and inorganic components toughen the matrix and result in a more impact-resistant COPV.

We took this a step further by developing an epoxy composite possessing a uniquely engineered morphology using a completely different self-healing agent, one which has inherent toughening AND self-healing characteristics combined. The novel resin technology is capable of toughening the matrix as well as healing microcracks through the use of a uniquely engineered composite morphology. An FRC containing the newly developed resin was resistant to micro-cracks and was able to repair physical damage. In particular, this resulted in both a reduction in micro-cracks within the bulk resin, as well as evidence of repairable damage due to cryogenic cycling, as witnessed in the recovery of impact and flexural properties of bulk and FRC test coupons, respectively. Mechanical property testing was performed on resin test bars, and strength was recovered after cryo-cycling and self-healing using impact testing (Figure 3). Fiber reinforced composites (FRCs) were fabricated using the novel resin and were likewise able to demonstrate recovery of mechanical properties in the FRC after cryo-cycling followed by self-healing via flexural testing.

FRC_FIG3

Figure 3: Impact resistance of epoxy test bars containing toughening and self-healing characteristics.

The developed micro-crack prevention and repair resin capability will be a drop-in technology, thus decreasing the overall cost of implementation and manufacturability. The resin can be used for filament winding, layup, or be prepregged. Additionally, as the FRC structures are more reliable, their expected usage life will be extended which is an additional cost-saving advantage.

Nanocomposites:

Self-healing is one technology that can be imparted through the use of nanocomposites; however, nanocomposites can also be used to improve the bulk mechanical properties of different neat materials by incorporating nanoparticles into the matrix. For instance, NEI has developed nanoadditives for elastomer seals. These nanoscale particles act as “network modifiers” that have chain characteristics and thus are reactive, bonding to the elastomer network. The altered network structure has unique properties that are not possible with simple nanoscale fillers. For example, the nanocomposite elastomer has improved stiffness while preserving the flexibility and stretchability of a rubber (see Figure 4). Improvements in modulus and hardness, without decreasing the elongation at break, have been obtained in these novel nanocomposite materials. As the network structure largely determines the mechanical properties of an elastomer, traditional fillers (e.g. clay and silica particles) – even if they are at the nanoscale – do not alter the network structure of the elastomer. Therefore, these particles bring unbalanced changes to the properties of the elastomer. That is, they invariably increase the modulus but decrease the elongation at break of the elastomer. NEI’s nanoparticle strategy is fundamentally different from that of conventional approaches. The nanoparticles have been designed to become part of the elastomer network and alter the network structure.

FRC_Fig.3

Figure 4: Nanocomposite elastomer seals (left) show an improvement in mechanical properties with increasing nanoadditive concentration (right).

The examples above present the platform for new technologies that introduce nanoscale additives as a means to create bulk, composite, or coating materials with unique morphologies and improved physical and chemical properties. NEI has the capabilities to develop novel nanocomposites materials that can be tailored to a specific application. These capabilities include nanoscale particle synthesis including electrospinning for nanofibers, surface functionalization of nanoparticles, and prototyping of bulk nanocomposites materials and fiber reinforced composites. We also have experience in the scale-up of processes through numerous commercial endeavors.

Case Studies in Designing New Nanoscale Materials

Core-Shell Particles

Core-shell

Example of core-shell nanoparticles produced at NEI Corporation

Core-Shell nanoparticles are composite particles where a core material is coated with a material of a different composition (shell), imparting unique functionalities that are otherwise unattainable for the individual materials. Such nanostructured particles have diverse applications. NEI Corporation has recently developed a patent pending, scalable process to produce core-shell nanoparticles. The process can be used to manufacture metallic and ceramic core-shell nanoparticles, such as metal / metal oxide and metal / metal boride core-shell nanoparticles. The versatility of the process allows core-shell nanoparticles to be synthesized in a wide range of compositions.

Applications:

  • Biomedical – in-vitro and deep tissue imaging
  • Solid propellants – launch vehicles, satellites, and missiles
  • Energetic materials – airbags, drug injection, and micro-valves
  • LEDs, lasers, and phosphors
  • Catalysis

 


Sulfide Nanomaterials

Lithium Tin Phosphorus Sulfide (LSPS) »

Lithium Tin Phosphorus Sulfide (LSPS) is a “superionic” solid that conducts lithium ions at room temperature. The patent pending solid electrolyte is designed to eliminate flammability issues associated with currently used liquid electrolytes, while providing high ion conductivity. At room temperature, the electrolyte has high lithium-ion conductivity (~10-3 S/cm) and can potentially be used in lithium-ion and lithium-sulfur rechargeable batteries. The processing methodology, which has been scaled to the kilogram level, can be adapted to other multi-element sulfide compositions.

Processes to produce tin (IV) sulfide (SnS2) nanoparticles (~100 nm), and micro-nano hybrid zinc sulfide (ZnS) particles, have also been developed at NEI.


Oxide Nanomaterials

Magnesium Oxide (MgO)

Magnesium oxide is commonly used as a grain growth inhibitor, desiccant, cement additive and an industrial cable insulator. Additional applications include visible and IR transparent windows, deacidification of at-risk paper items, protective coatings in plasma displays, and medicinal applications. We produce high surface area (specific surface area 10-15 m2/g, primary particle size ~150 nm) magnesium oxide nanoparticles.

We also produce and supply nanoparticles of yttrium oxide (cubic Y2O3), yttrium aluminum oxide (garnet, Y3Al3O12), and magnesium aluminum oxide (spinel MgAl2O4).


High Surface Area Hollow Silica Fibers

HSF_Fig1 HSF_Fig2

NANOMYTE® SuperSurf-C and SuperSurf-W are exceptionally high surface area, fibrous silica-based materials. Their nominal specific surface area (BET) is > 1000 m2/g. These materials are supplied in two forms: woven cloth (SuperSurf-C) and wool (SuperSurf-W). The fibers of these materials are hollow, which allows them to be infiltrated with other materials to achieve a desired functionality. The exceptionally high surface area of the fibers is due to the presence of nanoscale roughness and pores.

Applications:

  • Base for filters to remove hazardous materials from water & air
  • Antimicrobial textiles
  • Thermal insulators
  • Desiccants and sorbents
