Abstract:
In at least one embodiment, a fuel cell is provided comprising a positive electrode including a first gas diffusion layer and a first catalyst layer, a negative electrode including a second gas diffusion layer and a second catalyst layer, a proton exchange membrane (PEM) disposed between the positive and negative electrodes, and a microporous layer of carbon and binder disposed between at least one of the first gas diffusion layer and the first catalyst layer and the second gas diffusion layer and the second catalyst layer. The microporous layer may have defined therein a plurality of pores with a diameter of 0.05 to 2.0 μm and a plurality of bores having a diameter of 1 to 100 μm. The bores may be laser perforated and comprise from 0.1 to 5 percent of a total porosity of the microporous layer.
