Solid macromolecular electrolyte type fuel cell

摘要

A fluorine-based macromolecule is reinforced by a fibre to which surface treatment using a silane coupling agent is applied. A hydrocarbon-based macromolecule is graft-polymerised with the fluorine-based macromolecule. A sulphonic acid group is introduced into the resulting graft copolymer to obtain a macromolecular electrolytic film for a fuel cell.
