Abstract:
1. A fuel cell assembly comprising: a membrane electrode assembly including a membrane disposed between a plurality of catalyst layers; a plurality of diffusion media, each having a microporous layer disposed on a side thereof, wherein the side of said diffusion media having the microporous layer is adhered to the catalyst layers of said membrane electrode assembly; a first bipolar plate including a first working face and a second working face; a second bipolar plate including a first working face and a second working face; and an electrically conductive adhesive layer disposed on at least a portion of at least one of the first working face and the second working face of said first bipolar plate and said second bipolar plate, wherein said adhesive layer adheres said first bipolar plate to one of said diffusion media and said second bipolar plate to another of said diffusion media to minimize an electrical contact resistance between said diffusion media and said first and second bipolar plates.
