摘要

Low temperature solid oxide fuel cell (SOFC) has received great interest recently. However, the lowoxygen ion conductivity of electrolyte restricts the operation temperature reduction for SOFC. In thisreport, 2D nanomaterial Ti 3 C 2 T x is used as filler doped into the Sm 0.2 Ce 0.8 O 1.9 （SDC） to enhance theconductivity and mechanical strength of composite electrolyte. The 5wt.% Ti 3 C 2 T x /SDC compositemembrane exhibits the 3 and 9 times ionic conductivity as that of SDC at 500°C and 600°C, respectively.Furthermore, the peak power density of the single cell enhanced by ～250% at 500°C. The addition ofTi 3 C 2 T x -MXene also improved the hardness, fracture toughness and thermal stability of compositemembranes.
