Solid Oxide Electrolysis Cell (SOEC)

At the laboratory stage, ZrO3 with 8 mol% Y2O3 is usually used as the electrolyte, which is thermally and chemically stable to realize the transmission of cations at a high temperature. Usually, the high temperatures means better efficiency and more degradation.

Anion Exchange Membrane Water Electrolysis (AEMWE)

AEM water electrolysis technology combines the advantages of both the traditional alkaline water electrolysis and the PEM water electrolysis. Non-noble metal catalysts such as Ni, Co, and Fe can be used in alkaline media. Anion exchange membranes have similar advantages to proton exchange membranes, which also does not involve the alkaline liquid that may cause air pollution. The alkaline system avoids the extensive use of precious metals, meaning an significantly lower cost than that of PEM water electrolysis cells. At present, the restrictive element in the development of AEM water electrolysis technology lies in the performance of the anion exchange membrane. The anion exchange membrane is less stable in thermal and chemical properties with restricted level of anion conductivity, which limits the life and electrolysis performance of the AEM electrolytic cell.
