Hydrogen Production by Water Electrolysis: Progress and Suggestions
The increasing demand for carbon emission reduction has drawn wide attention on the green hydrogen-manufacturing technology. Hydrogen production by water electrolysis based on renewable energies has the lowest carbon emission among the main hydrogen manufacturing methods. This study summarizes the h...
