METHOD OF PRODUCING CATALYST, CATALYST, AND FUEL CELL

Disclosed is a method of producing a catalyst. The method includes: dispersing, in an acid solution, a composite in which a plurality of raw material microparticles containing a noble metal is supported on a carbon support doped with a nitrogen atom and a first transition metal atom; immersing a noble metal member in the acid solution; and alternately blowing a first gas containing an oxidizing gas and a second gas containing a reducing gas into the acid solution.
