ABSTRACT:
An electrode for solid polymer electrolyte fuel cell comprising a catalyst layer comprising at least electrocatalyst particles (3), a supporting substance therefor (4) and proton-conductive polymers (1) and (2), wherein the proton-conductive polymer (1) is present in a primary presence state in which the proton-conductive polymer (1) covers the electrocatalyst particles (3) or the supporting substance therefor (4), or both at least partly; the proton-conductive polymer (2) is present in a secondary presence state in which the proton-conductive polymer (2) binds the electrocatalyst particles (3) to one another or binds particles of the supporting substance (4) to one another or to the solid polymer electrolyte membrane; and the melt viscosity of the proton-conductive polymer (1) is lower than the melt viscosity of the proton-conductive polymer (2).
