Parameters identification and determination are important in the fuel cell model development, especially for multiphysic modeling which includes many sensitive semiempirical parameters. In this paper, the parameter sensitivities are investigated based on a well-developed 1.2-kW multiphysic proton exchange membrane fuel cell model. Moreover, to get a complete fuel cell system model, the models of auxiliaries...
Polymer electrolyte membrane (PEM) fuel cell systems convert chemical energy from hydrogen into electrical power via a reaction with oxygen. Fuel cells are highly efficient, nearly noiseless, and locally emission-free. However, safe and efficient operation requires special system temperatures, mass flow rates of the reaction gases, and a particular excess ratio and gas pressure on the anode and cathode...
Polymer electrolyte membrane (PEM) fuel cell systems are investigated as replacement for auxiliary power units (APU) that are currently used for electrical power generation on aircraft. PEM fuel cells are highly efficient energy converters and provide electrical energy, cathode exhaust gas with low oxygen concentration and water. The system investigated is intended for generation of oxygen depleted...
