Abstract:
A flow-guiding plate for a fuel cell, including a conductive sheet including a relief: defining alternating flow channels on first and second faces, two successive channels on the first face being separated by walls; defining first and second access holes at ends of each of the flow channels on the second face and of a first group of flow channels on the first face; defining a flow restriction in each flow channel of a second group of flow channels on the first face, the cross-section of the flow restrictions being smaller than the cross-section of the access holes to the flow channels of the first group, the first face including alternating flow channels of the first group and alternating flow channels of the second group.

Claim (Index 17):
A fuel cell comprising:\n first, second, and third guiding plates as claimed in  claim 1 ; first, second, and third membrane electrode assemblies each comprising a proton exchange membrane, a cathode, and an anode which are attached on either side of the proton exchange membrane; first and second gas diffusion layers; the first guiding plate forming a bipolar plate interposed between the first and second membrane electrode assemblies, the first gas diffusion layer covering the flow channels of the first face of the first guiding plate and being in contact with the first face and with the anode of the second membrane electrode assembly; the second and third guiding plates delimiting, between them, a flow circuit and forming a bipolar plate interposed between the second and third membrane electrode assemblies, the first face of the second guiding plate being in contact with the second face of the third guiding plate, the second gas diffusion layer covering the flow channels of the first face and being in contact with this first face of the third guiding plate and with the anode of the third membrane electrode assembly.
