Mathematical modeling of PEMFC stack for real time simulation

This paper presents a mathematical model of a proton exchange membrane fuel cell (PEMFC) with its integrated humidifier for real time simulation. The inlet air is humidified by a membrane-based passive humidifier which presents the advantage of not adding parasitic power loss in the system. Simulation results are validated with a Ballard 1.2-kW Nexa fuel cell system. For real time simulation, dSPACE real-time processor has been used. The model will be later integrated in an autonomous hybrid system with a wind turbine and an electrolyser.
