Title:
FUEL CELL ELECTROLYTE REINFORCED MEMBRANE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/027069
Kind Code:
A1
Abstract:
The present invention relates to a fuel cell electrolyte reinforced membrane, a membrane-electrode assembly comprising same and a fuel cell, and more specifically, to an invention that may provide a fuel cell material and a fuel cell exhibiting improved performance by providing a fuel cell electrolyte reinforced membrane comprising, from the cross-sectional view of the electrolyte reinforced membrane, a first electrolyte layer formed on one lateral surface of a porous support; and a second electrolyte layer formed on the other lateral surface. By introducing the porous support exhibiting improved mechanical properties by being manufactured under particular conditions such as draw ratio and drawing speed, the mechanical properties of the electrolyte reinforced membrane may be greatly improved, and the difference in mechanical properties between a first axial direction (length direction) and a second axial direction (thickness direction) may be minimized.
