The technological development of hydrogen-oxygen generators (water electrolysis hydrogen production equipment) is rooted in the evolution of water electrolysis hydrogen production technology. In 1800, Nichoson and Carlisle first extracted hydrogen and oxygen using electrolysis. In 1900, Schmidt invented the first industrial electrolyzer. In 1962, DuPont improved the proton exchange membrane and launched a civilian PEM hydrogen generator in the 1980s, initiating the PEM technology route.
In 1988, NEL was the first in the world to launch a non-asbestos diaphragm electrolyzer. In 1996, Proton OnSite in the United States began collaborating with United Technologies Aerospace Systems, holding a significant position in this field. In 2001, NHEL (the predecessor of NEL) launched its first pressurized electrolyzer to the market. In 2007, Cyrus acquired the relevant technology and developed four generations of hydrogen generator products.
In December 2018, Cysec's megawatt-class 50m³/h pure water electrolysis hydrogen production equipment entered the semiconductor industry. In September 2020, the company completed the mid-term acceptance of the National Key R&D Program project "MW-level Solid Polymer Electrolyte Water Electrolysis Hydrogen Production Technology". In 2021, a 250kW PEM electrolyzer, developed in cooperation with Sungrow Power, was demonstrated in Ordos. On December 9, 2021, Cummins Enze (Guangdong) Hydrogen Energy Technology Co., Ltd. was established to engage in the localization of PEM water electrolysis hydrogen production technology.
