Abstract
The performance of Ni-based trimetallic alloy cermet anodes, Ni0.8−xCu0.2Mx (M = Fe and Co; x = 0.1, 0.2, and 0.3)/Ce0.8Sm0.2O1.9 (SDC), was investigated for intermediate-temperature (500–700°C) solid oxide fuel cells (IT-SOFCs), using humidified (3% H2O) model syngas with a molar ratio of H2/CO = 3/2 as the fuel. Though doping Fe or Co 10 mol % into the Ni0.8Cu0.2/SDC anode led the cell performance to the increase, the cell performance decreased as Fe or Co content increased further. On the one hand, doping Fe or Co into the Ni0.8Cu0.2/SDC anode further effectively inhibited carbon deposition owing to CO on the anode. Our results suggest that the Ni0.7Cu0.2Fe0.1/SDC and Ni0.7Cu0.2Co0.1/SDC anodes are more promising materials than Ni0.8Cu0.2/SDC anode for syngas fuel in IT-SOFCs.
