Document Type and Number:
WIPO Patent Application WO/2023/098351
Kind Code:
A1
Abstract:
A hydrogen storage tank and a hydrogen storage system for a hydrogen energy railway vehicle. The hydrogen storage tank comprises a tank body made of a resin material and a hydrogen storage alloy filled in the tank body, wherein a hydrogen charging port and a hydrogen discharging port are provided on the tank body, several capillary heat exchange tubes are uniformly arranged in the hydrogen storage alloy and arranged parallel to an axis of the tank body, ends of the several capillary heat exchange tubes are in communication with each other and then extend from the tank body to serve as a medium inlet, and the other ends of the capillary heat exchange tubes are in communication with each other and then extend from the tank body to serve as a medium outlet. In the hydrogen storage system, a first heater plate is provided at a coolant inlet of a hydrogen stack, and a second heater plate is provided at the medium inlet of the hydrogen storage tank. According to the present invention, the weight of the hydrogen storage system is reduced, the hydrogen storage density by weight of the system is increased, the hydrogen charging/discharging rate is improved, the amount of sucked/discharged hydrogen is increased, and the hydrogen charging time is reduced.
