Title:
POROUS MATERIAL FOR ELECTROLYTE MEMBRANE FOR FUEL CELL, METHOD FOR PRODUCING THE SAME, ELECTROLYTE MEMBRANE FOR SOLID POLYMER FUEL CELL, MEMBRANE-ELECTRODE ASSEMBLY (MEA), AND FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2007/123267
Kind Code:
A1
Abstract:
Disclosed is a porous material for fuel cell electrolyte membranes, which is characterized
by comprising at least one reinforcing layer within a high porosity layer and/or
on the surface of the high porosity layer, and thereby having a multilayer structure
composed of the high porosity layer and the reinforcing layer. The porous material
for fuel cell electrolyte membranes is further characterized in that the average
pore size of the pores of the high porosity layer is different from the average
pore size of the fine pores of the reinforcing layer. This porous material has
high porosity and high strength, and thus is suitable as a base for electrolyte
membranes for solid polymer fuel cells. Also disclosed is a high-performance fuel
cell using such a porous material.
