Abstract
A means of inhibiting the occurrence of overvoltage in an electrode catalyst for fuel cells so as to substantially prevent reduction of fuel cell performance includes an anode electrode catalyst for fuel cells, which contains a carbon support having at least one pore having a pore size of 10 nm or less and a pore volume of 1.1 to 8.4 cm3/g and catalyst particles having particle sizes of 3.1 nm or less and supported by the carbon support so that the density of supported catalyst particles is 15% to 40% by mass.
