The invention discloses an inland ship methanol hydrolysis hydrogen production methanol engine and fuel cell hybrid power system and an operation control method thereof, belongs to the technical field of hybrid power propulsion, and solves the problem that hydrogen fuel and a methanol engine are difficult to apply to medium and large ships. The immersed pump is installed in the methanol storage tank and is responsible for conveying methanol to the evaporator and the methanol engine. The evaporator generates methanol steam to be supplied to the reactor, and the steam generator provides steam. Hydrogen-rich synthesis steam generated by the reactor enters a separator, and water vapor and hydrogen-rich synthesis gas are separated out. The hydrogen-rich synthesis gas is treated by the buffer tank and the purifier and is respectively conveyed to the methanol engine and the hydrogen fuel cell. Waste gas generated by the methanol engine and the hydrogen fuel cell is exhausted to the atmosphere, the methanol engine drives the generator through the transmission shaft, and electric energy generated by the generator and the hydrogen fuel cell is merged into a ship power grid after passing through the AC/DC converter. Efficient energy utilization and high reliability of an inland ship power system are achieved.
