Control method and system for hydrogen fuel cell in hybrid electric vehicle

The invention discloses a control method and system for hydrogen fuel cells in hybrid electric vehicles. The control method for the hydrogen fuel cells in the hybrid electric vehicles includes the steps of detecting a power supply module of a vehicle, judging the driving state at the moment in hybrid power, receiving a power-off signal from a hydrogen fuel cell control system in a parking state and then detecting power of a storage battery, allowing the hydrogen fuel cell control system to control the hydrogen fuel cells to continue working to charge the storage battery to a preset power threshold when the storage battery power is lower than a set value, and then allowing the hydrogen fuel cell control system to control the hydrogen fuel cells to reduce loading and shut down, otherwise thehydrogen fuel cells conduct direct load reduction and powering off. The control method and system for the hydrogen fuel cells in the hybrid electric vehicles have the advantages of ensuring safe andefficient operation of a w
