The invention aims to provide a ship ammonia-electricity hybrid power system based on integrated design of a fuel cell and an engine gas circuit. The ship ammonia-electricity hybrid power system comprises an ammonia fuel engine, a double-fed induction motor, a propeller, a gearbox, a diesel generator set, the fuel cell, an ammonia gas storage and supply system, a power transformation device, a ship power grid, a hydraulic element and the like. According to the technical scheme, hybrid propulsion of the ammonia fuel engine and the doubly-fed induction motor can be achieved, coordinated power supply of the diesel generator set, the fuel cell and the lithium battery is achieved, and the propulsion efficiency of the whole ship is further improved. A gas path coordination scheme of the engine and the fuel cell is provided, the advantages of the engine and the fuel cell can be complemented, the redundancy of gas path design is simplified, and the integration level of the system is improved.
