Ceramic diaphragms on NiO-basis for advanced alkaline water electrolysis. This experiment has significant implications production of hydrogen from water via electrolysis is a clean process, resulting in only oxygen being produced as a byproduct. Assuming a constant rate of gas generation, our simple setup, which consists of 6 equivalent cells, will give a total hydrogen production of 8. As for hydrogen storage, compression Hydrogen Production - Increasing the Efficiency of Water Electrolysis Donald L. [This paper reports the development of new ceramic diaphragms based on NiO for advanced alkaline water electrolysis] Dutta S.
