The invention discloses a ship and a hydrogen energy power system.The hydrogen energy power system comprises a hydrogen supply device, at least one fuel cell device, an energy recovery device and a master control device, the hydrogen supply device is connected with the fuel cell device, and the fuel cell device comprises a fuel cell, a storage battery and a controller; the controller is connected with the fuel cell and the storage battery and used for enabling the fuel cell to operate normally and be short-circuited periodically and enabling the storage battery to supply power when the fuel cell is short-circuited, and the main control device is connected with the fuel cell device and the energy recovery device and used for controlling the storage battery to supply power when a propeller of the ship rotates reversely. Kinetic energy of the ship is converted into electric energy to be stored in the energy recovery device, the energy recovery device discharges preferentially during acceleration and releases energy together with the fuel cell device to drive the ship, and load requirements under various working conditions are met through a hybrid power mode of a fuel cell, a storage battery and the energy recovery device. And control optimization is carried out aiming at the special application scene of the ship, and the method can be applied to various ships.
