Description
technical field [0001] The invention mainly relates to the technical field of hydrogen preparation, in particular to a device for preparing hydrogen by catalytic electrolysis. Background technique [0002] As the worldwide energy crisis and environmental crisis continue to intensify, new energy has become an increasingly important development direction, and hydrogen energy has become an important means to achieve carbon peaking and carbon neutrality. With the invention, development and industrialization of hydrogen fuel cells, a cleaner way to produce hydrogen is needed to achieve the effect of energy saving and emission reduction. The current production methods of hydrogen limit the popularization and application of hydrogen energy to a large extent. Hydrogen production by electrolysis of water is considered to be the main way to produce hydrogen, especially the use of solar energy and wind energy, which has a large fluctuation range and has an impact on the power grid, re...
