ELECTRODE CATALYST FOR FUEL CELL, ITS MANUFACTURING METHOD, AND ELECTRODE AND FUEL CELL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electrode catalyst for fuel cell which is high in catalytic activity and resistance to poisoning, its manufacturing method and an electrode and a fuel cell that uses this catalyst.

SOLUTION: The electrode catalyst for fuel cell includes a porous carbon, where 10 nm or less of diameter of pores have 0.6 to 1.2 ml/g of pore capacity, and 90 or higher vol.% of the pores are in the dimensions of 1.2 to 5.0 nm, and 0.5 to 3.0 nm of Pt particles are dispersed on the surface of the pores. The electrode for fuel cell and the fuel cell that use it are also disclosed.
