This invention relates to a composite conducting material comprised of a mixture of flake graphite and thermoplastic polymer powder sintered at high pressure that can be used for realizing a fuel cell electrode. The mixture comprises a first type of flake graphite composed of flakes having a granulometry between 10 and 100 &#x3bc;m and/or a second type of flake graphite comprised of clusters of particles of graphite linked and superimposed upon each other in such a fashion that their principal planes are parallel to each other; said clusters having a planar anisotropy and having between 10 &#x3bc;m and 1 mm in length and between 5 and 50 &#x3bc;m in thickness, the mixture also comprising a thermoplastic polymer powder having a granulometry between 10 and 200 &#x3bc;m, the flakes and/or the clusters having their principal planes parallel to each other.
