摘要： An electrode catalyst for fuel cells that can inhibit an increase in gas diffusion resistance includes a carbon material having a ratio of a peak intensity I A derived from an amorphous structure to a peak intensity I G derived from a graphite structure in an X-ray diffraction spectrum (ratio I A /I G ) of 0.90 or less as a catalyst-supporting carrier.
