PRESSURE-SENSITIVE ADHESIVE SHEET FOR CONVEYING ELECTROLYTE MEMBRANE AND METHOD USING SAID PRESSURE-SENSITIVE ADHESIVE SHEET TO MANUFACTURE FUEL-CELL MEMBRANE ELECTRODE ASSEMBLY

摘要

This invention provides a pressure-sensitive adhesive sheet for conveying an electrolyte membrane. When processing a membrane electrode assembly (MEA), said pressure-sensitive adhesive sheet can contribute to making it easier to handle a polymer electrolyte membrane being conveyed and preventing deformation and wrinkling of said polymer electrolyte membrane. This pressure-sensitive adhesive sheet for conveying an electrolyte membrane comprises a substrate and a pressure-sensitive adhesive layer positioned on one or both surfaces of said substrate. The pressure-sensitive adhesive layer(s) partially or completely lose(s) adhesiveness upon an external stimulus. In one embodiment, the pressure-sensitive adhesive layer(s) contain(s) thermally expandable microspheres.
