　　Double-perovskite Sr2FeNbO6(SFN),synthesized by solid state reaction method,has been applied to the hydrogen electrode of solid oxide electrolysis cells(SOEC)supported by YSZ electrolyte.SFN-YSZ composite electrodes were fabricated by screen-printing.Contrast tests were designed to investigate the electrochemical behavior of SFN.The reaction mechanism of the H2O reduction in SFN-YSZ hydrogen electrode was discussed.
