The proton membrane electrolysis water hydrogen production process adopted in this project is the electrolytic water hydrogen production technical route with the best coupling degree with wind power and photoelectricity at this stage. The project has the largest hydrogen production unit for electrolysis of water by proton exchange membrane in China, with an electrolysis power of 2.5 MW, making it more efficient in hydrogen production. Just as the engine is the core component of the car, the proton exchange membrane electrolysis water hydrogen production system is the core equipment of the project. It uses pure water as an electrolyte, does not add any chemicals during the electrolysis process, and has high current density and safety.
