STACK DESIGN FOR SOLID POLYMER ELECTROLYTE FUEL CELL

A fuel cell consists of several parts including a fuel (hydrogen), oxidant (air of pure oxygen), Membrane - Electrode Assembly (MEA) and several differrent controllers. In this research, design and construction of a stack of solid polymer electrolyte fuel cell with one kilo Watt capacity which includes bipolar, mono-polar and end plates, as well as cooling plates and sealing gaskets is considered. Furthermore, necessary calculations for construction of these materials are presented. It is shown that sixteen bipolar pates each with 8 mm thickness, two mono-polarplates each with 8 mm thickness and two end plates each with 2 mm thickness are required. In addition, eight cooling plates each with 10 mm thickness and forty four Teflon sealing gaskets each with 2mm thickness are needed. All these plates have dimensions of 23x17 cm2 and include slits for mixing or cooling of the operating fluids. Ultimately, seventeen stacks of MEA with thickness of 2.2 mm are determined to be needed for this 1KW fuel cell. The overall length of this stack is 30 cm while its volume is 9720 cm3 and its mass is calculated to he 45 Kg.
