摘要：: <P>PROBLEM TO BE SOLVED: To provide an electrode electrolyte which is inexpensive and easy to recover catalyst metals and is excellent in proton conductivity, processability (joining characteristics between a proton conductive membrane and a gas diffusion layer and an electrode layer) and durability against chemical degradation. <P>SOLUTION: A electrode electrolyte for a solid polymer fuel cell includes: a polyarylene block copolymer which has a polymer segment having a sulfonic acid group (A); and a polymer segment (B) having substantially no sulfonic acid group, wherein the polymer segment (B) having substantially no sulfonic acid has a structural unit represented by the formula (1). <P>COPYRIGHT: (C)2012,JPO&INPIT
