Title:
INK FOR FORMING FUEL CELL ELECTRODE CATALYST LAYER, METHOD OF PREPARING FUEL CELL ELECTRODE CATALYST LAYER USING SAME, FUEL CELL ELECTRODE CATALYST LAYER PREPARED THEREBY, AND MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2014/185698
Kind Code:
A1
Abstract:
The present invention relates to an ink for forming a fuel cell electrode catalyst layer, a method of preparing a fuel cell electrode catalyst layer using the same, a fuel cell electrode catalyst layer prepared thereby, and a membrane electrode assembly and a fuel cell containing the same. The ink for forming a fuel cell electrode catalyst layer uses a solvent in which a mobility of a hydrogen ion conductive polymer is 2.0-3.0 kHz-1 at a side chain, and is thereby capable of preparing a catalyst layer with a structure in which nano-sized hydrogen ion conductive polymer-catalyst integrated bodies are concentrated, and a fuel cell electrode catalyst layer prepared using the same and a membrane electrode assembly and a fuel cell containing the same can exhibit an excellent cell efficiency even in a condition of relative humidity of 0%.
