Abstract

Ni/SDC anode has been investigated as an alternative anode for using methane fuel and compared to the conventional Ni/YSZ anode. Moreover, to improve the cell performance, the porous SDC thin layer was coated on the pore of the anode by sol-gel coating. The mixed ionic and electronic conductive properties of SDC in reducing condition provided the additional reaction area beyond the TPB site. The governing reaction mechanism of methane in the Ni-based anode underwent through the partial electrochemical oxidation. The pyrolysis of methane causing carbon deposition likely occurred in the Ni/YSZ anode. However, carbon was hardly formed in the SDC coated Ni/YSZ anode due to electrochemical oxidation of methane in the entire anode and also deposited carbon could likely be oxidized electrochemically.
