There are provided a surface modified material comprising a base material, and one or more kinds of sulfonimide compound groups bonded onto the surface of the base material via one or more linking groups -A-Y'&#x2014; (A is a direct bond or an organic group. Y&#x2032; is a bonding site with the base material.); the sulfonimide compound group comprising, in its molecular structure, one or more linking groups -A-Y&#x2032;&#x2014; and two or more sulfonimide groups; as well as a fuel cell using the surface modified material for a catalyst layer. There is also provided a sulfonimide compound for surface modification comprising one or more reactive end groups -A-Y (A is a direct bond or an organic group. Y is a reactive functional group.) and two or more sulfonimide groups.

Surface modified material, sulfonimide compound for surface modification, and fuel cell

Provided is an electrolyte equipped with a hydrophilic portion having a cyclic quaternary ammonium salt and a hydrophobic portion bonded to the hydrophilic portion; and a fuel cell, a Li secondary battery, secondary battery and a primary battery using the electrolyte. The electrolyte has preferably a structure represented by the formula (A) or (B), wherein P' represents a hydrophobic portion, Rand Reach represents hydrogen, fluorine, a hydroxy group, or a hydrocarbon or fluorinated hydrocarbon group having from 1 to 10 carbon atoms, Rand Reach represents a hydrocarbon, fluorinated hydrocarbon, or a fluorocarbon group having from 1 to 10 carbon atoms, r and s each represents an integer of 0 or greater but not greater than 8 and satisfies 1&#x2266;r+s&#x2266;8, u represents an integer and satisfies 2&#x2266;u&#x2266;9, and Xrepresents a counter anion. 

Electrolyte, and fuel cell, Li secondary battery, secondary battery and primary battery using the electrolyte

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 &#x2014;(CONM)(CO)(SONM)(SO)&#x2014; (0&#x2266;i, 0&#x2266;i&#x2266;1, 0&#x2266;i, 0&#x2266;i&#x2266;1, 0&#x3c;i+i, ito iare each an integer, and M is proton, alkali metal, or alkali earth metal), 2&#x2266;m (m is an integer), and Rf, E, and Emay be each arbitrarily selected in the repeating unit.
