Fuel cell stack, has fuel cell that is held between end plates as pre-mounted component over fixing elements that connect end plates, where end plates are designed as cooling units

摘要

The stack (1) has two end plates that are designed as cooling units (3). A fuel cell is arranged between the end plates. The fuel cell has a diaphragm, a gas diffusion layer and an electrode plate and/or a bipolar plate. The fuel cell is held between the end plates as a pre-mounted component over fixing elements that connect the end plates. The diaphragm, the gas diffusion layer and the electrode plate and/or the bipolar plate are pressed and/or glued during pre-assembly. Heat-conductive material i.e. silicone foil, is arranged between the fuel cell and the end plates.
