FuelCells are electrochemical devices that convert the chemical energy ofa gaseous fuel directly into electricity. They are widely regardedas a potential future stationary and mobile power source. Theresponse of a fuel cell system depends on the airand hydrogen feed, flow and pressure regulation, and heat andwater management. In this paper, we develop a dynamic modelsuitable for the control study of fuel cell systems. Thetransient phenomena captured in the model include the flow andinertia dynamics of the compressor, the manifold filling dynamics (bothanode and cathode), reactant partial pressures, and membrane humidity. Itis important to note, however, that the fuel cell stacktemperature is treated as a parameter rather than a statevariable of this model because of its long time constant.Limitations and several possible applications of this model are presented.
