Energy management optimization method for hydrogen fuel cell configured for underwater propeller

The invention discloses a hydrogen fuel cell energy management optimization method configured for an underwater propeller. The method comprises the following steps: constructing a hydrogen fuel cell and underwater propeller simulation model; the resistance borne by the marine pod propeller is analyzed according to sensor data; a data set composed of resistance f borne by the underwater propeller, a battery remaining capacity initial value e and optimal energy-saving output power P1 enabling the endurance mileage to be maximum is obtained through simulation, the data set is divided into a training set and a test set, the training set is used for training a BP neural network, and the test set is used for checking the training effect of the neural network; after the sensor obtains real-time data of resistance and battery remaining capacity, the real-time data serve as input quantities and are substituted into the BP neural network, the optimal energy-saving output power in the current state is obtained through p
