Bipolar plates have to accomplish many functions in the fuel cell stack.Main functions are:distribution of fuel gas and air uniformly over the active areas;heat removal from the active area;conduction of current from cell to cell;preventing leakage of gasses and coolant.For uniform gas distribution...
Bipolar plates are used in fuel cells with multiple cells arranged in layers to form a stack for the distribution of gases, in particular hydrogen or oxygen, the removal of water, gas-tight separation between adjacent cells and also sealing with respect to the outside and cooling. In addition...
The bi-polar plate has a framework comprising two metallic plates (20) having recesses at two levels making up two circulation channels for fuel (21S,21l), with an internal space for refrigerant liquid, and providing a peripheral space permitting the placing of a casing (11) for the distribut...
