ABSTRACT The invention provides a high activity electrode catalyst for fuel cells whose catalytic activity due to an expensive noble metal, such as platinum, has been improved to a higher level through the use of an inexpensive material to enable a reduction in noble metal catalyst usage, a fuel cell in which the above high activity electrode catalyst is used, a membrane-electrode assembly in which the above high activity electrode catalyst is used, and a. gas diffusion electrode in which the above high activity electrode catalyst is used. Use is made of an electrode catalyst for fuel cells comprising a carbon material that contain catalytically induced turbostratic structures in parts of its structure and noble metal particles supported thereon, or an electrode catalyst for fuel cells comprising the catalyst mentioned above and a catalyst comprising carbon black and noble metal particles supported thereon as mixed together or an electrode catalyst comprising the catalyst mentioned above and carbon black as mixed together.
