NOVELTY - A compound having an aromatic ring is subjected to electrolytic oxidation polymerization on the surface of electroconductive porous support (6) to form fibril-like polymer. The obtained fibril-like polymer is baked to form carbon fiber on the porous support. The metal catalyst is supported on the carbon fiber. A solution containing ion conductive polymer is then coated on the carbon fiber by non-contact method. Thus, the electrode is manufactured.    USE - Manufacture of electrode for polymer electrolyte fuel cell (claimed) used as power supply for electric vehicles, electric power generation system and domestic use co-generation system.    ADVANTAGE - The method provides electrode excellent in catalyst performance and proton-conductivity. Polymer electrolyte fuel cell comprising the electrode has excellent electric power generation performance.
