SOLID POLYMER FUEL CELL-PURPOSE ELECTROLYTE MEMBRANE, PRODUCTION METHOD THEREFOR, AND MEMBRANE-ELECTRODE ASSEMBLY

摘要

In an electrolyte membrane (10) for a solid polymer fuel cell, sealing ri bs (12) of a predetermined height made of an electrolyte resin is formed int egrally with the electrolyte membrane (10). Using the electrolyte membrane, a membrane-electrode assembly (20) is formed, which is further processed int o a fuel cell (30). Thus, an electrolyte membrane and a membrane-electrode a ssembly which are capable of improving the sealing characteristic when incor porated into a fuel cell are obtained. Besides, a fuel cell improved in the sealing characteristic is obtained.
