31 mar 2018 · Combining a rechargeable battery or super capacitor with a fuel cell creates a hybrid system that can accommodate the variations in load that occur during service. The chapter presents an analysis of fuel-cell systems, and finally reviews the commercial status and future prospects of complete fuel-cell systems.
The main components are the fuel cell stack, an air processing sys-tem (e. g. a compressor and humidifier), the fuel gas supply, thermal management system etc. Other peripheral components are valves, pumps, electrical devices etc. Fuel like hydrogen (from a tank sys-tem) and air (ambient) are feed into the FCS.

This fuel cell online calculator performs approximate calculations of PEM fuel cell stacks and comparative calculations for stacks based on stamped and joined metal bipolar plates (Metal-BIP) and on carbon-based bipolar plates (C-BIP), considering internal coolant flow fields for each BIP type.
A key driver associated with increased commercialization of stationary fuel cells is cost. Costs for stationary fuel cell systems vary by type and application and include capital cost (equipment and installation), operating and maintenance (O & M) costs, and cost for fuel.
