A plurality of ventilation openings are formed in the protective cover; the hydrogen storage system comprises a hydrogen storage and supply system base, a hydrogen cylinder bracket, a hydrogen cylinder fixing device, an excessive hydrogen concentrated discharge port and a plurality of hydrogen cylinders; the hydrogen filling system is used for filling hydrogen into the hydrogen storage system, a hydrogen filling port is formed in the hydrogen filling system, and the hydrogen filling port is connected with a hydrogen filling pipeline; and the hydrogen supply system is connected with the hydrogen storage system and a fuel cell, conveys the hydrogen stored in the hydrogen storage system into the fuel cell, and comprises a hydrogen supply pipeline connected with the hydrogen filling pipeline, and the hydrogen supply pipeline is connected with the fuel cell. The system is compact in overall structure, light in weight, small in size, more stable in structural design and capable of adapting to driving of ships in complex and changeable marine environments, and meanwhile a space is saved.

Description

technical field [0001] The present invention relates to the technical field of marine fuel cell systems, in particular to a hydrogen storage and supply system for marine fuel cells. Background technique [0002] In recent years, the global hydrogen fuel cell industry has developed rapidly. Due to its advantages such as no pollution, no noise, and high energy conversion efficiency, it is widely used in various transportation tools such as automobiles and ships, as well as other energy and chemical fields. The demand is increasing year by year. As an excellent energy carrier, hydrogen has the advantages of cleanliness, high efficiency, and no pollution. The hydrogen fuel cell ship developed on the basis of fuel cell powered vehicles is one of the most promising technologies that can completely replace traditional diesel engine ships. Hydrogen fuel cells are used to power ships, and hydrogen fuel needs to be continuously replenished. Therefore, the safe and efficient storage a...

AI Technical Summary

Problems solved by technology

Due to the lack of hydrogen refueling facilities in the port, the construction cost of the facilities is high, the storage of gas cylinders in the cabin takes up too much space, and there are potential safety hazards, the space limitation of the cabin and the changeable driving environment of the ship put forward higher requirements for the overall design of the hydrogen storage system of the ship

[0004] Most of the currently developed fuel cell ships use hydrogen storage cylinders to store hydrogen at high pressure. In order to meet the mileage and power requirements, hydrogen storage cylinders often have a large number and occupy a large space on the ship, resulting in a waste of space resources on the ship.

Most of the existing high-pressure hydrogen storage cylinders use steel structure brackets. The volume and weight of the hydrogen storage system are too large to meet the hydrogen storage conditions, which is inconvenient for hoisting, and it is not suitable for the salt spray environment of the ocean; most of the existing high-pressure hydrogen storage cylinders Exposed to the external environment and directly in contact with the air, it is not conducive to the long-term stable operation of the gas cylinder in the sea salt spray environment, and it is easy to cause corrosion of the pipeline system and valves
