NOVELTY - Dispersion liquid containing carbonaceous microparticles and polymer particles distributed to catalyst metal solution containing catalyst metallic element, is prepared. Obtained dispersion liquid is sprayed in heating furnace (20), heated, liquid component in dispersion liquid is evaporated, and mixed aggregate (A) of carbonaceous microparticles, polymer particles and catalyst metal is formed. Polymer component from mixed aggregate is removed and heated, to obtain catalyst material.    USE - Manufacture of catalyst material used for fuel cell (claimed) e.g. polymer electrolyte fuel cell.    ADVANTAGE - The catalyst material has excellent activity, and the polymer electrolyte fuel cell using catalyst material has high efficiency. The specific surface area of catalyst metal and carbon particles is high and three-phase interface is formed by simple method using catalyst material.    DETAILED DESCRIPTION - Dispersion liquid containing carbonaceous microparticles for forming carbon particles and polymer particles distributed to catalyst metal solution containing catalyst metallic element, is prepared. The obtained dispersion liquid is sprayed in heating furnace as mist-like droplet and heated within the heating furnace. The liquid component in the dispersion liquid is evaporated, and mixed aggregate of carbonaceous microparticles, polymer particles and catalyst metal is formed. The polymer component from mixed aggregate is removed by catalyst-carrying carbon particles. The mixed aggregate is heated and catalyst metal is supported by porous and hollow carbon particles, to obtain catalyst material. Polymer particles containing organic polymer compound is different from carbonaceous microparticles. An INDEPENDENT CLAIM is included for fuel cell, which consists of anode having porous structure in which fuel is supplied, solid electrolyte having minute structure comprising oxide ion conductor, cathode having porous structure in which oxygen-containing gas is supplied and catalyst material contained in the anode and/or cathode.    DESCRIPTION OF DRAWING(S) - The drawing shows block diagram of manufacturing apparatus of catalyst material.    Heating furnace (20)    Mixed aggregate (A)
