Abstract

The invention provides a high-pressure hydrogen supply system for an external supplying type hydrogen filling station, which can fill hydrogen fuel for fuel cell powered vehicles. The hydrogen supply system mainly comprises a pipe bundle hydrogen conveying vehicle, a fixed high-pressure hydrogen storage tank group, a parallel multi-compressor pressurizing system, a high-pressure hydrogen filling system, and a data acquiring, processing and safety monitoring system. The high-pressure hydrogen supply system takes the pipe bundle hydrogen conveying vehicle as a part of a hydrogen storage container of the hydrogen filling station and makes the pipe bundle hydrogen conveying vehicle a first stage of the staged hydrogen storage container, adopts the pressurizing system consisting of multiple compressors which are connected in parallel, and introduces the data acquiring, processing and safety monitoring system. The high-pressure hydrogen supply system has the advantages of adjustable hydrogen storage volume, large operation flexibility, cost conservation, convenient maintenance, high service efficiency and so on.

Description

technical field

[0001] The invention belongs to the technical field of new energy, and relates to an external hydrogen refueling station that integrates hydrogen transportation, storage, compression, filling, data acquisition, processing and safety monitoring, and can provide high-pressure hydrogen filling for fuel cell vehicles. High pressure hydrogen supply system. Background technique

[0002] A series of problems such as air pollution, energy shortage, and climate warming force human beings to vigorously develop new energy utilization technologies. Because hydrogen has the advantages of wide sources, good recyclability, and environmental friendliness during use, fuel cell vehicle technology using hydrogen as fuel has become a research and development hotspot for governments and major energy and automobile companies. In recent years, fuel cell vehicle technology has become more and more mature, and various prototype vehicles have been launched one after another. Demonstr...

Embodiment Construction

[0039] The contents, advantages and objects of the present invention will be set forth in the following description of the embodiments.

[0040] According to the present invention, the hydrogen supply system is composed of subsystems such as hydrogen supply, compression, storage, filling, data collection, processing and safety monitoring.

[0041] According to the present invention, the hydrogen supply system of this embodiment is composed of 2 tube bundle hydrogen transportation vehicles 1a and 1b and 2 gas unloading columns. Two tube-bundle hydrogen transport vehicles send the gaseous hydrogen purified and compressed to 20MPa (maximum) from the hydrogen production plant to the hydrogen refueling station. When one tube-bundled hydrogen transport vehicle supplies hydrogen to the hydrogen refueling station, the other one can return to the hydrogen source for rotation. When the gas consumption of the hydrogen refueling station is large, two tube-bundle hydrogen transportation v...
