PROCESS FOR PRODUCTION OF CATHODE CATALYST LAYER FOR FUEL CELL, CATHODE CATALYST LAYER, AND MEMBRANE ELECTRODE ASSEMBLY FOR SOLID POLYMER FUEL CELL

摘要

Improving the use ratio of active sites in a catalyst having oxygen reduction activity so as to provide a cathode catalyst layer, etc. for a fuel cell with a high level of power generation performance. Using a process of introducing a functional group onto a surface of the catalyst 13 which has oxygen reduction activity and a process of blending the catalyst 13 with the functional group on the surface together with the electron conductive material and the proton conductive polymer electrolyte in order to prepare a catalyst ink for forming the cathode catalyst for the fuel cell.
