Title:
GAS DIFFUSION ELECTRODE SUBSTRATE FOR FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2013/172174
Kind Code:
A1
Abstract:
Provided is a gas diffusion electrode substrate that is for a fuel cell, has a low in-plane gas permeability and favorable water drainage characteristics in addition to high conductivity, and is able to exhibit high electricity generation performance across a wide temperature range from low temperatures to high temperatures. The gas diffusion electrode substrate for a fuel cell is characterized by a microporous section being disposed at least at one surface of an electrode substrate, and the microporous section containing flake graphite having an aspect ratio in the range of 50-5000.
