Electric Power

We’ve been supplying mesh solutions for fuel cells, batteries, and other clean energy sources for 25 years. We pioneered the technology often referred to as ‘Cold Bond’ in the industry – which provides rigidity and improved conductivity to the mesh in electrical applications.

Wire mesh is particularly suitable in these applications; depending on the weave it can have a very large surface area compared with foils and other flat metals while providing a level of flexure that these materials can’t. It is particularly effective when used in impregnation applications when a coating is applied or holding a slurry.

We source mesh from a wide variety of locations and also weave high-value alloys in the United States and Europe, enabling our customers to shore up their supply chains and have all manufacturing processes from wire, weaving, slit coils, cutting to size, and assembling the finished product completed in the domestic market.

Fuel Cells

The main types of fuel cells are listed below;

  1. Polymer Electron Membrane (PEMFC)
  2. Solid Oxide (SOFC)
  3. Alkaline (AFC)
  4. Molten Carbonate (MCFC
  5. Phosphoric Acid (PAFC)
  6. Direct Methanol (DMFC)

The first 3 are the most common, the latter are emergent technologies that will provide significant reliability and efficiency benefits as they move to commercialization.

We provide solutions for different types of fuel cells to a range of manufacturers. The porosity, conductivity and shape of wire mesh and cloth means it can be used in a variety of different applications within the fuel cell. The ‘peaks’ in the mesh provide depth that can penetrate more into the application and can withstand a considerable amount of flex without losing contact with active materials. We have developed specific mesh solutions to enhance the performance in the following areas:

  • Gas Diffusion Layer
  • Electrode current collector
  • Catalyst / Electrolyte substrate

Nickel and Nickel based alloys are most commonly used, including Crofer 22 H – UNS S44535 (DIN 1.4760), Ni 99.6% – S44535 (DIN 2.4060) and Duranickel. Other alloys (e.g. stainless, copper, aluminum, precious metals) are available based on the specific chemistry requirements.

When customers come to us, our application engineers work collaboratively together with them to develop the best solution for their application. We can provide a range of solutions from multi-layer sintered products – to single layer weaves that offer similar characteristics to multi-layer laminates or foil based products. Getting involved at the start of the project allows us to provide the lowest cost solution while meeting performance.

Batteries

We supply wire mesh and cloth to battery customers manufacturing primary and secondary batteries. It can be used as an electrolyte substrate or an electrode current collector.  Wire mesh and cloth are particularly suitable for these applications since they have an open area which allows for higher volumetric power densities, thus proving more effective compared to carriers made from a solid foil or other material.

Nickel is commonly used in electro-chemical applications, but other specifications often requested – AISI 304L, DIN W. 1.4306, AISI 316L, DIN W. 1.4404, Hastelloy C22, DIN 2.4602. However, our application engineers will work with you to determine the best alloy, mesh count, weave and porosity specifications for your requirements.
