Changchun Green has independently developed and formed a series of "hydrogen surge" PEM electrolytic cell products with a range of 50-250 Nm3/h. The technical autonomy rate of electrolytic cell parts has reached more than 80%, and the power consumption of hydrogen production is ≤4.3kWh/Nm3H2@1.8A/cm2. The fluctuation range is 8%-135%. After appraisal by an expert group organized by the China Renewable Energy Society, the overall technical level of the product has reached the international advanced level. The PEM electrolyzed water hydrogen production system equipped with a "hydrogen surge" electrolytic cell covers hundreds of millions to hundreds of megawatts in specifications. It can be widely used in green hydrogen substitution scenarios such as transportation, chemical industry, refining, and steel, achieving "double carbon" for my country. The goal is to inject green hydrogen power. The core technology of PEM hydrogen production equipment is independently controllable, key materials such as proton exchange membranes, catalysts, and carbon paper have been domestically replaced, and parameters such as DC power consumption and membrane electrode active area have reached the international advanced level.
