Yangzhou Jidao Energy Co., Ltd. released the first set of safe pressure-bearing shell-type single-tank hydrogen production water electrolysis cells with the largest production capacity. The hydrogen production capacity of the electrolytic cell reaches 1350m3/h, the maximum can reach 1500 m3/h, and the pressure is 2.5 MPa. It can save 50% of the land and 90% of the factory buildings. It truly opens a new era of large-scale construction and application, and has a number of internationally leading key indicators. At the same time, it also has the following advantages: a complete set of outdoor safe pressure-bearing shell electrolytic cell technology creates the era of green energy; Large-scale high-pressure electrolytic cell technology can reduce investment per unit of equipment by 20%, and DC energy consumption is lower than that of standard cubic meter of hydrogen by 4.2 kilowatt-hours, which is significantly better than the national first-level energy efficiency standard for large-scale electrolytic cells; this equipment will be used for hydrogen production and energy storage power stations, connected to the power grid control, realizing one-button start, unattended, remote monitoring, equipment interconnection and other functions; multi-electrolysis chamber circulation distribution technology allows the electrolytic cell to operate more smoothly and reduces system kinetic energy by 10%; Electrolytic cell anti-leakage online detection technology, cell automatic cleaning technology, internal circuit cooling technology.
