Abstract
An electrolyte having a structure where a fluorinated hydrophilic segment A represented by -E-[Rf-E]- and a hydrocarbon hydrophobic segment B are alternately bonded to each other through chemical bond and a production process therefor, and an electrolyte membrane, a production process therefor, a catalyst layer and a fuel cell using the same. Rf is a linear or a branched perfluoro chain having one or more carbon atoms, E, and Eare each a proton conductive portion represented by Formula —(CONM)(CO)(SONM)(SO)— (0≦i, 0≦i≦1, 0≦i, 0≦i≦1, 0<i+i, ito iare each an integer, and M is proton, alkali metal, or alkali earth metal), 2≦m (m is an integer), and Rf, E, and Emay be each arbitrarily selected in the repeating unit.
