REINFORCED SOLID POLYMER ELECTROLYTE COMPOSITE MEMBRANE, MEMBRANE ELECTRODE ASSEMBLY FOR SOLID POLYMER FUEL CELL, AND SOLID POLYMER FUEL CELL

摘要

The present invention provides a solid polymer fuel cell having improved stability over time. The solid polymer electrolyte composite membrane reinforced by the present invention is a reinforced solid polymer electrolyte composite membrane for a solid polymer electrolyte fuel cell comprising at least two polymer electrolyte membranes and at least one sheet porous stiffener, Wherein the sheet-like porous reinforcing material is substantially filled with the electrolyte of the polymer electrolyte membrane, and the porous reinforcing material on the sheet contains a peroxide decomposing catalyst.
