%X Gradient Ni-SDC anode and anode-supported SDC electrolyte were produced by tape casting method with laminating and co-sintering process. The best co-sintering temperature of gradient Ni-SDC anode and SDC electrolyte was 1300ˇăC for 3 h. The open porosity of gradient Ni-SDC anode sintered at 1300oC was 36%, which offered sufficient open porosity of more than 30%. By adjusting the composition of Ni in gradient anode, the thermal expansion coefficient (TEC) of Ni-SDC anode could be adjusted close to that of SDC electrolyte, which improve the compatibility of anode and electrolyte. The bending strength of gradient Ni-SDC anode was 134 MPa. The electrical conductivity of gradient Ni-SDC anode was better than that of non-gradient Ni-SDC anode at 650 - 800ˇăC.
