Experimental research on heating of fuel cell vehicle under cold environment

In this paper, aiming at the heating problem of fuel cell vehicles in low temperature environment, the principle, advantages and disadvantages of heat pump heating system and PTC heating system are analyzed. In addition, this paper takes a fuel cell bus as an example to analyze the application of PTC heating system in fuel cell vehicles. The results show that PTC heating is the most suitable vehicle heating method in low temperature environment, and the temperature rise rate of fuel cell bus is slow due to the large interior space. This paper also puts forward specific suggestions for the current vehicle heating scheme.
