ELECTRODE CATALYST FOR FUEL CELL, MEMBRANE ELECTRODE ASSEMBLY, FUEL CELL AND PORTABLE ELECTRONIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a carbon carrier on which a catalyst can be deposited excellently and which has high electronic conductivity and consequently to realize a high-performance electrode catalyst for a fuel cell and the fuel cell.

SOLUTION: The electrode catalyst for the fuel cell is characterized in that a catalytic metal is deposited on a mixture of carbon containing at least one of nitrogen, phosphorus, oxygen and sulfur on the surface with a carbon fiber on the surface of which a graphite C plane is exposed or another carbon fiber on the surface of which the edge of the graphite C plane is exposed. This invention provides the membrane electrode assembly, the fuel cell and the electronic equipment which mounted the cell.
