The invention discloses a marine internal combustion engine and fuel cell hybrid power system and a control method thereof. The marine internal combustion engine and fuel cell hybrid power system comprises an internal combustion engine power generation assembly, a fuel cell assembly, a storage battery pack, a bus, a driving motor assembly, a power coupling device, a propeller, direct-current electric equipment and alternating-current electric equipment. Electric energy generated by the internal combustion engine power generation assembly and the fuel cell assembly is output to the bus; the storage battery pack is connected with the bus; the bus correspondingly supplies the electric energy to the driving motor assembly, the direct-current electric equipment and the alternating-current electric equipment; the driving motor assembly drives the propeller to rotate through the power coupling device. The marine internal combustion engine and fuel cell hybrid power system has the beneficial effects that the fuel economy of the whole power system is improved; and the power generation efficiency and the energy recovery rate of the fuel cell assembly are improved. Stable control over the airinflow of fuel cells is achieved; and an iterative learning control algorithm is used for controlling an electric valve, and accurate and rapid gas supply to the fuel cells under different working conditions is achieved.
