The invention discloses a control method of a fuel cell hybrid electric vehicle system and belongs to the field of B60W or B60K classification. The fuel cell hybrid electric vehicle system comprises a fuel cell pack, a single-stage boost inverter, a storage battery pack and an electric motor. According to the control method, an upper computer communication module gives out a power instruction according to the different operating situations of a hybrid electric vehicle, and a system control module calculates the power required by fuel cells according to the matching degrees of the fuel cells, storage batteries and alternating current side output power at the previous moment, sends a fuel cell power control signal and direct-connection duty ratio to a fuel cell control module and a motor driving module respectively and controls required input-output powers respectively. A storage battery charge capacity detecting module detects the charge capacity and other information of the storage batteries, and the system control module decides to charge the storage batteries or not through calculation and controls charge and discharge of the storage batteries according to the fuel cell power control signals and the direct-connection duty ratios. By means of the control method of the whole system, the system cost is reduced, and the system reliability is improved.
