To provide a grafted polyimide electrolyte exhibiting excellent proton conductivity and gas barrier properties, an electrolyte membrane for a fuel cell and a catalytic layer for a fuel cell, each comprising the electrolyte, a membrane-electrode assembly comprising the electrolyte membrane and/or the catalytic layer, and a fuel cell comprising the membrane-electrode assembly.
The grafted polyimide electrolyte comprises a main chain bearing an imide group of a six-membered ring structure and a side chain bearing a sulfonic group. The electrolyte membrane for a fuel cell and the catalytic layer for a fuel cell each comprise the grafted polyimide electrolyte. The membrane-electrode assembly comprises the electrolyte membrane for a fuel cell and/or the catalytic layer for a fuel cell. The fuel cell comprises any one of the electrolyte membrane for a fuel cell, the catalytic layer for a fuel cell and the membrane-electrode assembly.
