Abstract: PROBLEM TO BE SOLVED: To provide a new electrode electrolyte for a polymer fuel cell, which can maintain a high proton conductivity even at a high temperature and does not have embrittlement of the membrane caused, and has eliminated any of problems such as deterioration of power generation output of the fuel cell and failure of power generation due to fracture of the membrane. SOLUTION: The electrolyte contains a sulfonated polyarylene based copolymer consisting of a structure block (hydrophobic block) as expressed by the formula (1') which has a branch point and does not have a sulfonic group and a structure block (hydrophilic block) having a sulfonic group as expressed by a formula (5).

Abstract: PROBLEM TO BE SOLVED: To provide a branched sulfonated polyarylene polymer that has high proton conductivity by increasing the amount of introduced sulfonic acid groups while at the same time it is difficult to be swollen under elevated temperature and humidified conditions and has excellent dimensional stability. SOLUTION: An aromatic compound represented by formula (1) is provided. A polyarylene polymer can be synthesized with the use of the aromatic compound. COPYRIGHT: (C)2010,JPO&INPIT
