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...

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.
