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