Description
technical field [0001] The invention belongs to the technical field of hydrogen production by electrolysis of water, and in particular relates to an evaluation device and evaluation method of alkali liquor for electrolysis of hydrogen production. Background technique [0002] Hydrogen is regarded as the most ideal energy carrier due to its green, low-carbon, high efficiency, storage and transportation advantages. Using renewable energy such as wind power and photovoltaics to electrolyze water to produce hydrogen is one of the most important production methods for hydrogen in the future. At present, the electrolytic water hydrogen production technology mainly includes alkaline electrolytic water hydrogen production, solid polymer electrolytic water electrolysis hydrogen production and solid oxide water electrolysis hydrogen production. The scale of the equipment is relatively large, so it is currently the main technology for hydrogen production by electrolysis of water. [...
