Products Applications

The Hydrogen Electrolysis Rectifier is a DC power supply device used to produce hydrogen by electrolyzing water. It converts AC power into DC power to provide the required electrical energy for the electrolyzer, thereby decomposing water molecules to produce hydrogen and oxygen. This type of equipment is essential for achieving green energy transformation and hydrogen economy.

Application Industry

*Photovoltaic, wind power, wave power, biomass power(green power) are connected to the power sourcerectifier and the electrolyzer to electrolyze hydrogen production

*Electrolytic hydrogen production by power source rectifer connected to conventional power grid and integrated with electrolyzer

*Inverter system between hydrogen energy storage and power grid
