“…The O 1s XPS spectrum of PLNCu is presented in Figure c. The peak at 529.2 eV is attributed to the lattice oxygen (O α ), while the peak at 532 eV is related to the surface oxygen (O β ). − In general, the surface oxygen is considered to be the active oxygen on the surface of PLNCu. Obviously, PLNCu has more surface oxygen (stronger O β peak) because of its special crystal structure, and the high surface oxygen vacancies are conducive to the oxygen electrode reaction.…”

Proton-conducting solid oxide electrolysis cells (H-SOECs) have attracted a lot of attention due to their high efficiency, energy-saving ability, and environmental friendliness. The ideal H-SOEC oxygen electrode materials are tripleconducting oxides with mixed proton (H + ), oxygen ion (O 2− ), and electron (e − ) conductivity. Herein, the triple conductive oxide Pr 2 NiO 4+δ (PNO)-based perovskite (Pr 0.9 La 0.1 ) 2 (Ni 0.8 Cu 0.2 )O 4+δ (PLNCu) is chosen as the oxygen electrode of the H-SOEC with impressive electrochemical performance. Its crystal structure, physicochemical property, and cell performance are discussed in detail. The thermal expansion coefficient of the PLNCu sample is 13.78 × 10 −6 K −1 , and the electrical conductivity is 258 S cm −1 at 450 °C. Moreover, the polarization resistance of the single cell is as low as 0.056 Ω cm 2 , and the current density at 1.3 V can reach 1.61 A cm −2 at 750 °C, which shows good electrochemical performance. A 100 h long-term test also shows that the cell has good performance and structural stability. Therefore, this work highlights a novel oxygen electrode material (Pr 0.9 La 0.1 ) 2 (Ni 0.8 Cu 0.2 )O 4+δ for proton-conducting solid oxide electrolysis cells.
