摘要：

La0.4Sr0.6TiO3 (LST) nanofibers are prepared by electrospinning method, the LST nanofiber scaffolds are sintered on YSZ (8 mol% Y2O3-92 mol% ZrO2) electrolyte flakes, and Gd0.2Ce0.8O1.9 (GDC) and Ni infiltrate into La0.4Sr0.6TiO3 nanofiber scaffolds. In this paper, the nanofiber-based LST-GDC-Ni composite anodes are tested in H-2 or CH4 fuel gas, respectively, and show excellent thermal and redox cycling stability. Carbon deposition appears on the surface of nanofiber-based LST-GDC-Ni composite anodes after being fed with CH4 fuel gas for 100 h. The amount of carbon deposition is proportional to the mass ratio of Ni:LST. A small amount of carbon deposition boosts the electrochemical performance, however, a large amount of carbon deposition is the opposite. The optimal mass ratio of LST:GDC:Ni has been found to be 1:1:0.4. (c) 2018 Elsevier Ltd. All rights reserved.
