Physically Motivated Heater Model for Precise Gas Temperature Control in Fuel Cell Stack Test Beds

A physically motivated heater model for precise gas temperature control for use in fuel cell stack test beds is proposed. Additionally, a parameter identification method based on modulating functions is provided. The applicability of the identification method and the model is validated through simulations and real-world experiments. Lastly, a time-optimal controller based on the identified model is evaluated on a fuel cell stack test bed.
