Control-oriented cold start modelling and experimental validation of PEM fuel cell stack system.

The cold-start of proton exchange membrane fuel cell (PEMFC) has been one of the leading technical challenges for fuel cell vehicle commercialization. During the cold start process, a new control-oriented modelling methodology of a water-cooled PEMFC stack system was present. The voltage and temperature change throughout the stack may be forecast using the model technique. Then the model was validated in a 5 Kw, 20 cells, water-cooled stack at room and subzero temperatures. The result shows that the model accuracy can capture the stationary and transient states of the fuel cell stack well. For the cold start of PEMFCs in automotive applications, the suggested model may be utilized to investigate real-time state estimates and model-based control approaches. • A model is developed by the control volume and thermal resistance network method. • The cold start experiment is conducted to verify the time and space distribution. • The proposed model can be used to study the real-time cold start control strategy.
