摘要：
A flooding phenomenon is suppressed in a high current density loading region so as to attempt the improvement of cell performance of fuel cells. An electrode catalyst for fuel cells, in which a catalyst comprising an alloy catalyst composed of a noble metal (1) and one or more transition metals (2) and having surface characteristics such that it shows a pH value in water of 6.0 or more is supported on conductive carriers, and a fuel cell using such electrode catalyst for fuel cells, are provided.
