• Dielectric CaCu₃Ti₄O₁₂ (CCTO) was used as electrolyte in low-temperature solid oxide fuel cells for the first time.

• A new heterostructure electrolyte was designed based on CCTO and Ni_0.8Co_0.15Al_0.05LiO_2−δ (NCAL). Promising ionic conductivity and high fuel cell performance were achieved

• CCTO–NCAL realized an electrolyte function due to its good dielectric property and a heterojunction effect.
