Yttria-stabilized zirconia (YSZ) supports with directional straight open pores were prepared by an alginate self-organization method. Ni nano-particles were impregnated into the porous supports to obtain the anodes for solid oxide fuel cells. The results show that the pore size of YSZ supports decreases with the increase of solid content and CaCl2 solution concentration. The open circuit voltage of Ni-YSZ/YSZ/LSM-SDC cell is above 1 V at 650 ℃ and the maximum power density at 800 ℃ is 225 mW/cm2 by using hydrogen as fuel and air as oxidant. It is expected that the output performance of the cell could be further improved by adjusting the porosity of the anodes and the thickness of electrolyte, and the application of the ceramics with straight open pores straight ceramics in solid oxide fuel cell could be realized.
