固体氧化物电解（SOE）可以用于以非常高的效率以显著的氢气生产率生产氢气。通过微结构和组成改性，传统的低成本固体氧化物燃料电池（SOFC）材料已被用于创建固体氧化物电解电池（SOEC），其可以在电池电压下实现显著的电流密度，从而允许比当前商业电解槽更高的转换效率。电流密度超过6 A/cm 2，电池电压< 1.67 V，在800 ℃下实现。该电池显示出比现有商业电解槽更高效率的氢气生产速率增加了3倍以上。
Solid Oxide Electrolysis (SOE) can be used to produce hydrogen with very high efficiencies at remarkable hydrogen production rates. Through microstructural and compositional modification, conventional low cost Solid Oxide Fuel Cell (SOFC) materials have been used to create a Solid Oxide Electrolysis Cell (SOEC) that can achieve remarkable current density at cell voltages allowing higher conversion efficiency than current commercial electrolysers. Current densities in excess of 6 A/cm 2 have been achieved at 800 ◦ C with a cell voltage of < 1.67 V. This cell shows a more than 3-fold increase in hydrogen production rate at higher efficiency than established commercial electrolysers.
