Provided is a simplified method for manufacturing an electrode for fuel cells, in which a separate process for forming a catalyst layer is not needed. The method involves applying a slurry containing a catalytic metal precursor, a catalyst carrier with micropores, an ionomer with cation exchange groups, and a solvent to a gas diffusion layer to form an unreduced catalyst layer, and thermally treating the unreduced catalyst layer in a reduction atmosphere to reduce the catalytic metal precursor to form a catalytic layer having catalytic metal particles embedded in the micropores of the catalyst carrier. Since the catalyst layer is formed during the formation of the electrode, the electrode comprising the catalyst layer can be conveniently manufactured within a short time, without the need to separately form the catalyst layer. The simplified method takes a short time and is also advantageous in terms of manufacturing equipment requirements and costs. An electrode fuel cell with good electrochemical activity and improved catalytic efficiency can be manufactured with the method.
