Abstract
A fuel cell stack assembly is provided which includes a first bipolar plate, a second bipolar plate, a sub-gasket, and a gas diffusion layer. The second bipolar plate may define a bypass channel with the first bipolar plate. The bypass channel includes at least one embossment formed therein. The gas diffusion layer may be disposed between the first bipolar plate and the second bipolar plate while the sub-gasket is sandwiched between metal bead seals formed in each of the first bipolar plate and the second bi-polar plate.
