FIELD: chemical or physical processes.
SUBSTANCE: invention relates to electrode catalyst for fuel cells. Electrode catalyst for fuel cells contains carbon material with ratio of peak intensity IA, obtained from amorphous structure, to peak intensity IG, obtained from graphite structure in X-ray diffraction spectrum (ratio IA/IG), equal to 0.90 or less, as carrier supporting catalyst.
EFFECT: invention makes it possible to prevent increase of gas diffusion resistance.
