Solid oxide electrolysis cell (SOEC) industrialization has been developing for many years. Commercial materials such as 8 mol% Y2 O3 -stabilized zirconia (YSZ), Gd0.1 Ce0.9 O1.95 (GDC), La0.6 Sr0.4 Co0.2 Fe0.8 O3-δ (LSCF), La0.6 Sr0.4 CoO3-δ (LSC), etc., have been used for many years, but the problem of mismatched thermal expansion coefficients of various materials between cells has not been fundamentally solved, which affects the lifetime of SOECs and restricts their industry development. Currently, various solutions have been reported, such as element doping, manufacturing defects, and introducing negative thermal expansion coefficient materials...
