Recently, the proton exchange membrane electrolysis water hydrogen production system, the first domestic island "green hydrogen" comprehensive energy demonstration project, successfully produced hydrogen. The project relies on the abundant wind energy resources of the island to build a hydrogen production-hydrogen storage-based 100% new energy power generation system. The fuel cell cogeneration system realizes the energy conversion from clean electricity to clean gas in a true sense, with zero carbon and 100% clean energy in the whole process.
