PROBLEM TO BE SOLVED: To provide an electrolyte membrane for a fuel cell which prevents deterioration (decomposition) due to radicals generated from hydrogen peroxide and has sufficient film formability and shape retention. A fuel cell electrolyte membrane comprising a fluorine-based ion exchange resin and a phenolic low-molecular compound represented by the following formula (1). [Chemical 1] (Wherein, X1 is, H independently, CH 3, OCH 3, or CH 3-n (CH 3) is any one of n, X2 is, H, CH 3, OCH 3 , CH 3-m (It is either (CH 3 ) m or OH. X1 may be different or the same. N and m are each a number of 1 to 3.) [Selection figure] None |
