ABSTRACT:
A method for making an electrochemical cell electrode involves depositing a layer of mechanically blended dry catalyzed carbon powder and dry hydrophobic polymer powder on the surface of a substrate by dispersing the mixture of powders as a cloud in a chamber over the substrate and pulling the powder onto the substrate by drawing a vacuum under the substrate. The method is particularly adapted to the high speed manufacture of electrodes.
