| 摘要 |
A process for producing an electrode for solid polymer electrolyte fuel cell by fixing a mixture of dispersions of proton-conductive polymers, electrocatalyst particles and a catalyst-supporting substance therefor, comprising mixing a solution or dispersion, in water or in a solvent, of a first proton-conductive polymer of a first MI value and a precursor of the first proton-conductive polymer having a second MI (melt index measured at 270°C, according to ASTM standard D1238) value of at least 10, electrocatalyst particles and catalyst-supporting substance therefor, to produce a catalyst at least partly covered with the first-proton conductive polymer; and mixing the obtained catalyst with a dispersion, in water or in a solvent, of a second proton-conductive polymer having a third MI value lower than the first MI value, a precursor of the second proton-conductive polymer having a fourth MI (melt index measured at 270°C, according to ASTM standard D1238) value in a range of 0.1 to 100. |
