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 1):
A flow guiding plate for a fuel cell, comprising:\n a conducting sheet including a first flat part, a second flat part, and flow channels extending between the first flat part and the second flat part, the flow channels including flow channels on a first face of the conducting sheet and flow channels on a second face of the conducting sheet, the second face being opposite to the first face, wherein the flow channels on the first face alternate with, and are parallel to, the flow channels on the second face such that two successive flow channels on the first face are separated by walls delimiting a flow channel on the second face, wherein the flow channels on the first face include a first group of flow channels and a second group of flow channels, wherein each flow channel of the first group of flow channels on the first face and the flow channels on the second face include a first access orifice at the first flat part and a second access orifice at the second flat part, and a cross section of each of the flow channels between the first access orifice and the second access orifice is greater than a cross section at the first access orifice and at the second access orifice, wherein each flow channel of the second group of flow channels on the first face includes a flow restriction at the first flat part and at the second flat part such that a pressure drop across each flow channel of the second group is greater than a pressure drop across each flow channel of the first group, a cross section at each of the flow restrictions of the flow channels of the second group being smaller than the cross section at the first access orifice and at the second access orifice of the flow channels of the first group, and wherein the first face comprises an alternation of flow channels of the first group and of flow channels of the second group.
