Problems solved by technology

[0003] PEM water electrolysis hydrogen production is different from traditional alkaline water electrolysis hydrogen production. PEM water electrolysis hydrogen production uses perfluorosulfonic acid proton exchange membrane with good chemical stability, proton conductivity and gas separation as solid electrolyte instead of asbestos membrane. It can effectively prevent the transfer of electrons and improve the safety of the electrolyzer. However, during the use of the existing hydrogen production fuel cell power generation system, most fuel cells currently cannot adjust the power generation efficiency according to the power consumption demand of the power consumption module.

Abstract

The invention discloses a fuel cell power generation system based on pure water electrolysis hydrogen production. The system comprises a hydrogen production module, a power generation module and a controller, wherein the hydrogen production module conveys produced hydrogen to the power generation module through a pipeline, and a hydrogen flow adjusting device and a controller are arranged on the pipeline between the hydrogen production module and the power generation module. The invention relates to the technical field of power generation systems. According to the invention, a PEM electrolytic bath structure is adopted to realize pure water electrolysis hydrogen production, a PEM core electrolysis system is designed, a reverse reaction principle of electrolyzed water is adopted to design a fuel cell power generation system, a power generation module indicates the hydrogen flow of a hydrogen production module through a floating ball and measures the hydrogen flow of the hydrogen production module through a transmitter so as to adjust a fuel cell module equipped with the fuel cell module, so that the power generation efficiency of the fuel cell module can be optimal; and the parts of the related structure cooperate with each other, so that the hydrogen production module is matched with the power generation module so as to improve the optimal power generation efficiency under different electric quantity requirements.

Description

technical field [0001] The invention relates to the technical field of power generation systems, in particular to a fuel cell power generation system based on pure water electrolysis for hydrogen production. Background technique [0002] The International Hydrogen Energy Council predicts that the total global demand for hydrogen in 2030 will be about 14 EJ (EJ), and the demand for hydrogen in the oil refining, chemical, and synthetic ammonia industries is the largest. The existing hydrogen production industry system is very mature, and more than 95% of the world's hydrogen uses fossils. Fuel production, steam-methane reforming is the most important method of hydrogen production, accounting for about 48%, followed by petroleum and coal gasification hydrogen production, and about 4% of hydrogen is obtained through water electrolysis. China is currently the world's largest In the country of hydrogen production in China, the existing industrial hydrogen production capacity is ab...
