MANUFACTURING METHOD OF MEMBRANE ELECTRODE CONJUGANT, MEMBRANE ELECTRODE CONJUGANT, AND POLYMER ELECTROLYTE TYPE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a membrane electrode conjugant capable of obtaining easily and certainly the membrane electrode conjugant having an anode in which an excellent CO poisoning resistant property and an excellent electrode property can be obtained even when a carbon carrier of the catalyst layer of the anode is reduced (especially the carbon carrier is eliminated).

SOLUTION: The manufacturing method of the membrane electrode conjugant 9 comprises a first process in which the membrane electrode conjugant 9 having an anode 1A which contains as an electrode catalyst a particulate containing Pt and Ru as an constituent element is manufactured and a second process in which the potential of the anode 1A is maintained at a potential of +0.98 Vvs.SHE or higher.
