Abstract: To solve the problems of short service life of battery and we study the hybrid power system composed of fuel cell (FC), battery and unidirectional DC/DC converter. In order to achieve a reasonable energy distribution and reduce the hydrogen consumption of the fuel cell, we propose an optimised control strategy based on the Pontryagin's minimum principle (PMP). We also propose a fuzzy optimal control strategy based on fuzzy control. This is optimised by changing the parameters in the membership function with the teaching-learning-based-optimisation (TLBO). Based on the simulation software, we build a simulation model to realise the real-time simulation of the two control strategies. The simulation results show that compared to fuel cell powered alone, the hydrogen consumption is reduced by 10.1% when using the fuzzy optimisation control strategy, and the hydrogen consumption is reduced by 12.7% when using the optimal control strategy based on PMP.
