摘要： A solid polyelectrolyte membrane for a fuel cell, comprises a synthetic resin comprising main chains and side chains, the main chains having a copolymer structure of a first olefin hydrocarbon and an olefin perfluorocarbon, the side chains having a sulfonic acid group containing crosslinked copolymer structure of a second olefin hydrocarbon and a diolefin hydrocarbon. The solid polyelectrolyte membrane is an inexpensive, solid polyelectrolyte membrane for fuel cells, of which the water content is controlled so that it does not cause too much wetting of electrode catalysts.

摘要： The present invention is a grafted polymer electrolyte membrane prepared by first preparing a precursor membrane comprising a polymer which is capable of being graft polymerized, exposing the surface of the precursor membrane to a plasma in an oxidative atmosphere, then graft-polymerizing a side chain polymer to the plasma treated precursor membrane and introducing a proton conductive functional group to the side chain. The resulting grafted polymer electrolyte membrane has excellent stability and performance when used in a proton-exchange membrane fuel cell or for electrolysis of water.

摘要： A disassembly method for membrane electrode assembly for fuel cell, and a disassembly method for fuel cell are provided, disassembly methods which are advantageous for the recovery of catalysts that are included in catalytic layers by making structural destruction of the catalytic layers progress by means of expanding a volumetrically-expandable material inside the catalytic layers. In such a state that a catalytic layer includes a volumetrically-expandable material that is capable of expanding volumetrically, the volumetrically-expandable material, which is included in the catalytic layer, is expanded by means of expansion treatment. Next, expansion of the volumetrically-expandable material, which has undergone volumetric expansion in the catalytic layer, is cancelled.
