| Abstract: An apparatus of an aspect includes a fuel cell catalyst layer. The fuel
cell catalyst layer is operable to catalyze a reaction involving a fuel
reactant. A fuel cell gas diffusion layer is coupled with the fuel cell
catalyst layer. The fuel cell gas diffusion layer includes a porous
electrically conductive material. The porous electrically conductive
material is operable to allow the fuel reactant to transfer through the
fuel cell gas diffusion layer to reach the fuel cell catalyst layer. The
porous electrically conductive material is also operable to conduct
electrons associated with the reaction through the fuel cell gas
diffusion layer. An electrically conductive polymer material is coupled
with the fuel cell gas diffusion layer. The electrically conductive
polymer material is operable to limit transfer of the fuel reactant to
the fuel cell catalyst layer. |
