Abstract
Oxygen reduction on carbon supported platinum catalysts has been
investigated in H3PO4, H3PO4-doped Nafion and PBI polymer
electrolytes in a temperature range from 80 to 190°C. Compared
with pure H3PO4, using the H3PO4 doped Nafion and PBI polymer
electrolytes can significantly improve the oxygen reduction
kinetics. Further enhancement of the catalytic activity can be
obtained by operating the polymer electrolytes at higher
temperatures. Efforts are being made to develop a polymer
electrolyte membrane fuel cell for operation at temperatures
between 150 to 200°C.
