| Abstract | (Ti,Nb)(3)SiC2 possesses high oxidation resistance and electrical conductivity in cathode side, endowing it potential application as intermediate-temperature solid oxide fuel cell (IT-SOFC) interconnects. However, the performances of (Ti,Nb)(3)SiC2 in anode side must be well understood before the application comes true. In this paper, the oxidation resistance and electrical conductivity of (Ti,Nb)(3)SiC2 in simulated anode reducing atmosphere are sys-tematically investigated. The oxidation kinetics follows parabolic law with a kP value of 7.57 x 10(-14) g(2) cm(-4) s(-1). The formed single oxide layer is composed of uniformly distrib-uted Nb-doped rutile TiO2 and amorphous SiO2, without carbon deposition. High partial pressure of H-2 and CO in simulated anode reducing atmosphere inhibit the oxidation by H2O and CO2. Nb doping with strengthen the Ti-O bond can also slow down the oxidation rate. ASR of (Ti,Nb)(3)SiC2 after 605 h cyclic oxidation is 1.6 and 3.7 mc] cm(2) at 800 degrees C and 500 degrees C, respectively. The low ASR comes from the induced extra electrons by Nb doping and the dissolution of H2O and H-2 in oxide, and the integrated TiO2 conductive network in the scale. (Ti,Nb)(3)SiC2 exhibits superior performances in simulated anode reducing atmosphere, making it an promising candidate for SOFC interconnect. (C) 2020 Hydrogen Energy Publications LLC.
