Abstract

Belonging to the technical field of new energy, the invention discloses a fuel cell standby power high pressure hydrogen supply system. The system includes a hydrogen self-feeding unit, a hydrogen filling and receiving unit, and a security control unit. The hydrogen self-feeding unit and the hydrogen filling and receiving unit are connected by pipelines, and the hydrogen filling and receiving unit and the security control unit are connected by leads. The invention provides a safer and more effective high-density fuel cell standby power high pressure hydrogen supply system, the greatest characteristics of which lie in that while substantially improving the system hydrogen storage density, the system application scope is expanded, the usage convenience and safety of the system are enhanced, and meanwhile, by optimizing the design and manufacturing process of a composite hydrogen storage bottle, the manufacturing cost of a high pressure hydrogen storage bottle used for standby power is substantially reduced.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a high-voltage hydrogen supply system for a fuel cell backup power supply. Background technique [0002] Under the dual pressure of increasingly scarce oil resources and increasingly serious environmental pollution, people are forced to pursue the maximization of energy utilization efficiency and the minimization of emissions. Due to the high energy efficiency and low emission of low-carbon fuels, gaseous fuels will occupy an increasingly important position in the near future, from liquefied petroleum gas, coal gasification synthesis gas, natural gas, and finally hydrogen. Since hydrogen has the characteristics of wide sources, high efficiency, environmental friendliness and sustainability during use, it is an ideal secondary energy source, and it can be predicted that it will play an important role in the future energy structure. [0003] Combined use with fuel cells is the mo...
