[0002] A polymer electrolyte where a proton conductive polymer (A) and a polymer (B) that is different from (A) are mixed with each other, characterized in that the ratio of the amount of unfreezable water, represented by formula (S1) in the above described polymer electrolyte, is no less than 40 wt% and no higher than 100 wt% is used, and thereby, the above described object can be achieved. ( ratio of amount of unfreezable water ) = ( amount of unfreezable water ) / ( amount of low melting point water + amount of unfreezable water ) × 100 ( % )",
