75 kW stack breathing

This work was conducted to analyze the control of fuel cell stack breathing at the system level. The model simulates the transient power response to step changes in current density for a 75 kW gross power PEM fuel cell stack. The system consists of the fuel cell stack, humidifier, compressor, and manifold dynamics. A schematic of the modeled system is shown below.
