Solid Oxide Electrolyzer Cell
Fuel Electrode ( e . g ., Ni-YSZ )
Electrolyte ( YSZ )
Oxygen electrode ( e . g ., LSM ) more hydrogen per unit of electricity input , making the process both cost-effective and environmentally friendly .
SOEC electrolyzer efficiencies currently stand at approximately 80 % with heat utilization , surpassing AE and PEM counterparts , which hover around 65 %. According to the
International Energy Agency ( IEA ), research and development efforts aimed at enhancing efficiency , through new materials or reversibility principles , could potentially push SOEC efficiency up to 90 % by 2050 . This potential increase in efficiency could significantly reduce LCOH , offering a substantial long-term advantage over AE and PE .
