Abstract: Sub-zero cold start is a major obstacle for PEM fuel cell vehicle's commercialization. This paper aims to study the sub-zero cold starting process of hybrid fuel cell vehicle. A thermo-electro-mechanical coupling model was built based on the electro-chemical and thermal dynamic performance of battery and fuel cell, as well as the mechanical dynamic performance of fuel cell's auxiliary system. A computational model was also set up based on MATLAB/simulink. Through simulations under different heat powers, the energy consumption and battery state of charge are analyzed, which help to optimize power train's configuration and control strategy.

Key words: PEM hybrid fuel cell vehicle, power train system, sub-freezing start up, stack warm up, simulation experiment research
