20090029219 | CATALYST, PROCESS FOR PRODUCING THE CATALYST, MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL - This invention provides a highly active and stable catalyst, which is suitable for use in fuel cells while suppressing the amount of expensive noble metals used, i.e., platinum (Pt) and ruthenium (Ru), and a process for producing the catalyst, and a membrane electrode assembly and fuel cell using the catalyst. The catalyst comprises: an electro conductive support; and catalyst particles supported on the electro conductive support and having a composition represented by formula (1) | 01-29-2009 |
20090050484 | PROCESS FOR PRODUCING MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL USING THE MEMBRANE ELECTRODE ASSEMBLY PRODUCED BY THE PROCESS - This invention provides a process for producing a membrane electrode assembly which has high and stable catalytic activity, and suppressed deterioration in catalytic activity during operation, and can prevent a deterioration in performance attributable to a structural factor of the membrane electrode assembly. The process comprises the step of, after the washing/removing step, drying the catalyst electrode in an atmosphere having a lower oxygen partial pressure than the air. The anode/cathode is a covered catalyst electrode having a structure formed by supporting/depositing a catalytically active material composed mainly of platinum/ruthenium subjected to the potential holding step, the washing/removing step, and the drying step, on a porous electroconductive carrier to cover at least a part of the porous electroconductive carrier with the ion conductive material. | 02-26-2009 |
