1. A method for making an electrochemical cell electrode comprising the steps of:

  • floccing a co-suspension of carbon particles and hydrophobic fluorocarbon polymer particles;

    drying the floc so produced and reducing it to a powder;

    resuspending the floc powder in an inking vehicle to form an ink;

    screen printing the ink onto a porous substrate to form a layer;

    drying the layer to remove the inking vehicle;

    compacting the layer;

    sintering the compacted layer; and

    catalyzing the layer.
