A low-cost electrode with great performance for anion exchange membrane fuel cells. It can also be used for alkaline fuel cells or batteries with liquid electrolyte (flow-through or static). This electrode is comprised of a carbon paper substrate and a carbon supported platinum electrocatalyst. This loading is designed for cost sensitive applications where platinum catalyst still plays a primary role in the electrochemical system without compromising the performance. Use of Fumion dispersion within the electrocatalyst layer greatly improves the hydroxyl ion conductivity for the anode and cathode electrochemical reactions and hence superb reaction kinetics. The first of its kind in the fuel cell and battery industries.
The Gas Diffusion Layer (GDL) used is a PTFE treated carbon paper with MPL that is designed for high performance fuel cell applications, which is 200 microns thick. PTFE treatment on the base fabric and MPL layer makes this substrate ideally suited for anion exchange membrane fuel cells, alkaline fuel cells, or battery applications using liquid electrolytes and gaseous reactants.
