1 DEVELOPMENT OF A BIPOLAR ELEMENT FOR PE-FUEL CELLS DEMONSTRATION IN A 6 kW STACK

The bipolar plate is the main construction element of a fuel cell stack. It needs to be optimized with respect to material and design. A bipolar element for a 200 cm2 active area fuel cell stack has been designed and manufactured. The versatility of the element has been demonstrated by the construction of a 100 cell stack. The stack exhibits a specific power of 330 W/kg at the nominal power of 6.4 kW.
