A gas diffusion electrode medium 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 cell performance across a wide temperature range from low temperatures to high temperatures. The gas diffusion electrode medium is characterized by a microporous region being disposed at least at one surface of an electrode substrate, and the microporous region containing flake graphite having an aspect ratio of 50-5000. |
