Fuel cells and fuel cell catalysts

摘要

A direct organic fuel cell (10) includes an anode (12) within an anode enclosure(18), solid polymer electrolyte (14), and gas diffusion cathode (16) within a cathode enclosure (20). An electrical load is connected between the anode (12) and cathode (16) via electrical linkage (22). A liquid fuel comprising between about 10 % and 95 % by weight formic acid is supplied to the anode enclosure. Oxidant is supplied to the cathode enclosure. Gas removal ports (24 and 26) are provided to remove carbon dioxide and water from the fuel cell.
