FUEL CELL WITH A HIGH DENSITY OF MEMBRANE-ELECTRODE ASSEMBLIES SHARING A COMMON FLUID CAVITY

摘要

The fuel cell comprises a first element (3) including at least two membrane-electrode assemblies (1a, 1b) in which electrodes of a same type (4a, 4b) are arranged on a same face of said first element (3), and a fluid cavity (C) to supply the electrodes of the same type (4a, 4b) of the first element (3) with fluid. It comprises a second element (5) including at least two membrane-electrode assemblies (1c, 1d) in which electrodes of a same type (4c, 4d) are arranged on a same face of said second element (5), and it comprises a fluid distribution plate (2) interposed between the first element (3) and the second element (5), said distribution plate (2) delimiting, with the first element (3) and the second element (5), the fluid cavity (C) common to the electrodes of the same type (4a, 4b, 4c, 4d) of said first and second elements (3, 5). The membrane-electrode assemblies (1a, 1 b) share a first common membrane and the assemblies (1c, 1d) share a second common membrane. Each membrane locally comprises anodes and cathodes intended to form the membrane-electrode assemblies (1a, 1 b, 1c, 1d).
