Catalyst transfer film for polymer electrolyte fuel cell, catalyst layer-electrolyte membrane laminate and polymer electrolyte fuel cell obtained using the same

摘要

PPROBLEM TO BE SOLVED: To provide a catalyst transfer film for a polymer electrolyte fuel cell capable of manufacturing a catalyst layer-electrolyte membrane laminate free from distortion in uniform transferring property, and to provide a catalyst layer-electrolyte membrane laminate obtained by using this, and the polymer electrolyte fuel cell. PSOLUTION: The catalyst transfer film for the polymer electrolyte fuel cell is such that (1) a catalyst layer is formed on a film substrate; (2) at least two through holes are installed on the surface on the side not coming in contact with the catalyst layer of the film substrate; (3) the through hole has a diameter of 1-100 m; and (4) the shortest distance between the through holes is 1 cm or less.
