Pressure, flow and thermal control of a fuel cell system for electrical rail transport

This paper presents the flow, pressure and temperature control of a fuel cell used in high power rail transport. We present modeling and control approach of the proton exchange membrane fuel cell and its auxiliaries. This work shows that we can characterize and adjust the system control on an operating cycle using the established simulation tools, not only to follow the requested power trajectories but also to control voltage, pressure and temperature of all elements to not be destructive.
