| 摘要 |
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 ).
