Carbonaceous Catalysts for H3P04 Fuel Cells.

Kocite trade mark materials have been evaluated as low cost air andor fuel electrocatalysts in phosphoric acid electrolyte fuel cells. Kocite materials are composite structures consisting of pyropolymers chemically bonded to refractory substrates. Fuel cell electrodes were fabricated and tested as anodes or cathodes in model fuel cells with conventional Pt fuel electrodes as counter electrodes. The research efforts have been divided into two parts. First, the performance of Kocite materials as electrocatalysts has been studied. The bulk of the program has been directed toward evaluating the performance of Kocite materials as platinum catalyst supports.
