Title:
POLYMER ELECTROLYTE FUEL CELL
Document Type and Number:
Japanese Patent JP2020064786
Kind Code:
A
Abstract:
To provide a polymer electrolyte fuel cell that is equipped with a fuel electrode and an air electrode having excellent catalytic activity (catalytic action) despite the low content of platinum group metals, can generate sufficient electricity using the fuel electrode and air electrode, and can supply sufficient electric energy to a load.SOLUTION: A fuel electrode 13 and an air electrode 14 forming a cell 11 of a polymer electrolyte fuel cell 10 are constituted by at least one platinum group metal selected from various platinum group metals, and at least three transition metals selected from various transition metals, and are formed into thin plate shapes having a porous structure in which a large number of fine channels are formed by firing a metal fine powder mixture in which the platinum group metal fine powder obtained by finely pulverizing at least one selected platinum group metal and the transition metal fine powder obtained by finely pulverizing at least three selected transition metals are uniformly mixed and dispersed after compressing the metal fine powder mixture into a thin plate with a predetermined area.SELECTED DRAWING: Figure 3
