US Patent Application 20100068592 - Electrodes for use in hydrocarbon-based membrane electrode assemblies of direct oxidation fuel cells
InventorsAssigneesUS Classes429/33, Electrolyte composition chemically specified429/40, Catalytic electrode structure or composition502/101, Making catalytic electrode, process only429/42, Having organic constituent as part of the electrode429/30Solid electrolyteAttorney, Agent or FirmInternational ClassesH01M 8/10H01M 4/00 H01M 4/88 Abstract textElectrodes for use in direct oxidation fuel cells (DOFCs) comprise, in sequence: an electrically conductive gas diffusion layer; a catalyst layer; and a proton-conducting layer. Membrane electrode assemblies (MEAs) comprise cathode and anode electrodes of such type sandwiching a proton conductive polymer electrolyte membrane (PEM), with the proton-conducting layer of the electrodes in contact with opposite surfaces of the PEM. Also disclosed is a method for fabricating the MEAs. |
