Ceramic Diaphragms on NiO ‐ Basis for Advanced Alkaline Water Electrolysis

A new, ceramic diaphragm on for the advanced alkaline water electrolysis has been developed. This fine‐pored, Ni‐gauze‐supported diaphragm has good mechanical properties, very low electrical surface resistance, good separation capability for the product gases and , and excellent corrosion stability in hot up to 120°C, and its manufacturing procedure is, furthermore, very simple. The integration of this diaphragm into an advanced electrolysis cell of "filter press" type is discussed.
