PURPOSE: An electrode for a polymer electrolyte membrane fuel cell is provided to reinforce mechanical strength and to maintain the thickness of a catalyst layer after long time driving by adding carbon nano fibers to an electrode catalyst layer of a fuel cell. CONSTITUTION: An electrode for a polymer electrolyte membrane fuel cell comprises, 100.0 parts by weight of a catalyst, 20~80 parts by weight of hydrogen ion conductive polymer electrolyte binder, 1~60 parts by weight of carbon nanofiber, 1~20 parts by weight of radical inhibitor. The carbon nano fiber is one selected from the group consisting of carbon nanotubes with 5~100 nm size, carbon nanofiber, carbon nanowires, carbon nanohorns, and carbon nanorings, and their mixture. |
