摘要： A fuel cell stack having a plurality of fuel cells arrange adjacent one another and compressed together. At least one of the fuel cells has an electrode plate with a flow field formed therein, a proton exchange membrane and a compressible fluid-permeable diffusion media that is disposed adjacent the electrode plate. A compressing member is operable to vary a compression of the fuel cells during operation which varies an intrusion of the compressible diffusion media into the flow field in the adjacent electrode plate. The variation of the intrusion of the diffusion media into the flow fields allows the control of the pressure drop across the fuel cell stack and enables the fuel cell stack to be dynamically controlled so that a desired operational state is achieves.

摘要： A fuel cell comprises an electrode plate having a flow field formed therein and a proton exchange membrane. A compressible permeable diffusion media is disposed adjacent the electrode plate. The diffusion media is compressed against the electrode plate so that a portion of the media intrudes into the flow field. A fuel cell stack can be made by compressing a plurality these fuel cells together. The fuel cell stack is compressed so that the diffusion media in each fuel cell is compressed against the adjacent electrode plate with a portion of the media intruding into the flow field in the adjacent electrode plate. The compression of the fuel cell stack can be adjusted so that a magnitude of intrusion of the diffusion media into the flow channels is adjusted and a pressure drop of a predetermined magnitude occurs across the fuel cell stack at a desired operational state.
