GAS DIFFUSION LAYER CONTAINING INHERENTLY CONDUCTIVE POLYMER FOR FUEL CELLS

摘要

A gas diffusion layer (13, 13A) comprises a porous material and an electrically conductive material coating at least a portion of an external surface of the porous material, wherein the electrically conductive material comprises at least one inherently conductive polymer. When placed adjacent to or in contact with a cathode (15A) of a polymer electrolyte or proton exchange membrane (PEM) fuel cell, the gas diffusion layer helps deliver oxygen to the cathode. The gas diffusion layer may be placed adjacent to or in contact with an anode (15) of a PEM fuel cell (10) to help deliver hydrogen to the anode.
