ABSTRACT:
A solid-polymer-electrolyte membrane for a polymer-electrolyte fuel cell is formed of a synthetic resin. The synthetic resin includes a main chain, and a hydrocarbon-based side chain. The main chain is formed as a film, and formed of a copolymer made from a fluorocarbon-based vinyl monomer and a hydrocarbon-based vinyl monomer. The hydrocarbon-based side chain involves a sulfonic group. The solid-polymer-electrolyte membrane exhibits a high strength and flexibility, but a low electric resistance, and can be produced at a reduced manufacturing cost. Thus, the solid-polymer-electrolyte membrane can be effectively applied to construct polymer-electrolyte fuel cells.
