摘要：

The properties of support-anode of Ni-YSZ reduced at isothermal and increasing temperatures were investigated. The results show that at < 600℃, the anodes exhibit the Ni agglomeration, the non-uniform microstructure and low bending strengths of 4.32 and 14.31 MPa when the reductions at isothermal and increasing temperatures occur, respectively. However, at >600℃, the anodes show the uniform microstructure, proper mechanical strengths of 14.92 and 56.63 MPa when the reductions at isothermal and increasing temperatures occur, respectively. The porosities of supported-anode firstly increase and then decrease with increasing the reduction temperature, and its maximum values appear at 700 and 400℃ for the reductions at isothermal and rising temperatures, respectively. Therefore, for both the reduction processes, the optimized reduction temperature for Ni-YSZ anode-supported SOFCs is not lower than 600℃. ©, 2015, Chinese Ceramic Society. All right reserved.
