Methanol hydrogen production energy-storage fuel cell base station standby power supply system and control method thereof

Abstract

The invention discloses a methanol hydrogen production energy-storage fuel cell base station standby power supply system and a control method thereof. The system comprises a methanol reforming hydrogen production machine, a hydrogen energy power supply, a controller, a solidification hydrogen storing system, a first control valve, a second control valve, a hydrogen compressor, a hydrogen dehydration system, wherein the methanol reforming hydrogen production machine, the hydrogen energy power supply and the solidification hydrogen storing system are mutually connected; the first control valve is arranged between the methanol reforming hydrogen production machine and the hydrogen energy power supply, and the second control valve is arranged between the solidification hydrogen storing system and the hydrogen energy power supply; and the methanol reforming hydrogen production machine, the hydrogen dehydration system, the hydrogen compressor and the solidification hydrogen storing system are sequentially connected. The energy storage efficiency of the system is much higher than that of direct application of a compressed hydrogen gas cylinder, fuel refreshment is carried out extremely conveniently, and people only need to fill methanol when fuels are discovered to be insufficient by remote monitoring and do not need to replace a container which is required in compressed hydrogen replacement, thereby greatly improving the transport efficiency and the safety.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a fuel cell power supply system, in particular to a fuel cell base station backup power supply system for hydrogen production from methanol and energy storage. Background technique [0002] The most commonly used backup power supply for communication base stations is composed of lead-acid batteries, which must always be in a floating charge state during use, which consumes a lot of energy and has a short life. The manufacturing process and the disposal of used batteries will have no impact on the environment. At present, there are also some backup power sources prepared by hydrogen fuel cells, which have the advantages of no pollution, no consumption of large amounts of energy in the standby state, and thus a long service life and low overall cost. [0003] However, after the reserve hydrogen source is used up, the hydrogen source needs to be provided in a timely manner. Some re...

Problems solved by technology

[0003] However, after the reserve hydrogen source is used up, it is necessary to provide the hydrogen source in a timely manner. Some reports we have seen now mainly use bottled compressed hydrogen, which takes up a large volume for storage, and the replacement and transportation process is not safe. Professionals are required to operate
