Description

technical field [0001] The invention relates to the technical field of hydrogen collection by electrolysis of water, in particular to a hydrogen collection device for hydrogen production by electrolysis of water based on solar power generation. Background technique [0002] In traditional hydrogen production methods, fossil fuels produce more than 90% of the world's hydrogen. Hydrogen production from fossil fuels mainly produces high-purity hydrogen by combining steam reforming and pressure swing adsorption. The use of electric energy to electrolyze water to produce hydrogen also occupies a certain proportion. Hydrogen production by solar energy has only been developed in the past 30 to 40 years. So far, research on solar hydrogen production has mainly focused on the following technologies: thermochemical hydrogen production, photoelectrochemical decomposition hydrogen production, photocatalytic hydrogen production, artificial photosynthesis hydrogen production and biologi...

Problems solved by technology

So far, research on solar hydrogen production has mainly focused on the following technologies: thermochemical hydrogen production, photoelectrochemical decomposition hydrogen production, photocatalytic hydrogen production, artificial photosynthesis hydrogen production and biological hydrogen production. Direct current can directly electrolyze water to produce hydrogen, but in the existing hydrogen production by electrolysis of water, the rate of hydrogen production is relatively unstable, which makes the compression and collection of hydrogen unstable
