The invention discloses an energy management method for reducing hydrogen consumption of a fuel cell hybrid energy system. The method comprises the following steps: establishing a fuel cell hybrid energy system; a load is connected to the other side of the direct current bus, and the fuel cell hybrid energy system is connected to a direct current microgrid to provide required power for the load; a parasitic hunting algorithm is used for optimizing decision parameters of an external energy maximization strategy, and power supply energy provided by a hydrogen fuel cell is reduced to the maximum extent by maximizing power supply energy provided by a lithium battery and a super capacitor; according to the optimal hydrogen fuel cell power, the lithium battery power and the lithium battery SOC, the charging/discharging voltage of the super capacitor and the lithium battery reference power are calculated, and the lithium battery reference current and the hydrogen fuel cell reference current are obtained, so that the minimum hydrogen consumption of the hydrogen fuel cell is obtained. The hydrogen consumption of the fuel cell is reduced, the service life of the fuel cell is prolonged, and the stability of the hybrid energy storage-supply system is improved.
