The solid oxide fuel cell is a kind of all-solid-state fuel cell for energy conversion. In this paper, the Prr0.5Sr0.5Co0.8Cu0.2O3–δ (PSCC) cathode material was prepared with the sol–gel method, and the Ce0.85Gd0.15O1.925 (SDC) electrolyte material was prepared through glycine combustion. The PSCC and SDC were mixed in proportion and synthesized into the composite cathode PSCC-xSDC (x = 20, 30, 40, 50, 60, wt.%). Through XRD observation, good chemical compatibility was shown between PSCC and SDC. When x = 50, the impedance and power density of cathode symmetric battery and single battery were the best. The Impedance value of PSCC-50SDC/SDC/PSCC-50SDC symmetric battery was 0.029 Ωcm2 when at 800 °C and the power density of single battery was 428.18 mW/cm2.
