ELECTROLYTE MEMBRANE FOR POLYMER ELECTROLYTE FUEL CELL CELL, ITS MANUFACTURING METHOD, AND MEMBRANE ELECTRODE ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an electrolyte membrane and a membrane electrode assembly capable of enhancing the sealing property of a cell for a fuel cell; and to provide the fuel cell cell having enhanced sealing property.

SOLUTION: A rib 12 for sealing having a height of 10-500 μm made of electrolyte resin integrating the electrolyte membrane 10 by melting is integrally formed in the electrolyte membrane 10 for a cell of a polymer electrolyte fuel cell. The membrane electrode assembly 20 in which the polymer electrolyte membrane is extended from a gas diffusion electrode and a separator is formed by using the rib, and the fuel cell cell 30 is assembled.
