FUEL CELL, JUNCTION OF ELECTRODE AND ELECTROLYTE MEMBRANE, ELECTRODE SUBSTRATE WITH CATALYST LAYER, PROCESS OF MANUFACTURING SAME, AND TRANSFER SHEET

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell and a junction of electrodes and electrolyte membranes, which can prevent characteristic deterioration caused by an excess of moisture, and suppress extreme decline of gas diffusifility occurring locally, and to provide a process of manufacturing the same and a transfer sheet.

SOLUTION: Catalyst layers are formed on both sides of an ion conductive electrolyte membranes, a plurality of through holes which penetrate the catalyst layer in a thickness direction are dispersed all over a region, where the catalyst layer is formed, at least on one side, and the through holes are made so as not to make communicative connections with one another.
