Amsen Technologies Tucson, AZ
Fuel cell technology can provide an alternative means for storing energy, both in stationary sources and in transportation, but its current reliance on precious metals can make it cost prohibitive for many applications. Fuel cell manufacturing would benefit from developing higher-performance polymer electrolyte membranes utilizing non-precious metal catalysts. Amsen Technologies is developing such membranes, which it thinks can serve as an alternative to Nafion and other expensive membranes used in fuel cells today.

Gerard Daniel's electro-chemical meshes are used in fuel cells, batteries, and electrolyzers. Uses for the mesh include membrane or electrode substrates, current collectors, flow field screens, and gas diffusion electrodes. We offer our exclusive ColdBond™ product, which provides performance benefits to the electro-chemical industry that other woven and non-woven products can not offer. With our proprietary ColdBond™ process, wire cloth can be metallurgically bonded so that the wires are welded at their crossover points. This fusing enhances mesh rigidity, improves conductivity and eliminates wire fraying. These properties give woven wire cloth superior processing characteristics in tracking, mechanical strength, and eliminate dangerous sharp edges for handling that are common with expanded and perforated metals. Wire cloth thickness can be precisely controlled to provide very thin material that is ideal for electrodes.
