The impact of gases arising from the gasification of wood chips on the performance of an intermediate temperature solid oxide fuel cell (IT-SOFC) has been assessed. The anode material was a 60:40 wt.% Ni:CGO-10 (Ce0.9Gd0.1O1.95) cermet, which was tested in various gas atmospheres from diluted hydrogen to emulated gasification mixtures containing H-2, N-2, CO, CH4 and CO2. It was found that CO decreased the performance of the cell when compared to H-2. The presence of 10% CO2 in the fuel did not significantly affect cell performance, whilst operation with 5 and 10% CH4 resulted in poor power output due to carbon deposition. The current-voltage characteristics of the cell in hydrogen compared well with theoretical I/V predictions. The latter enable leakage currents, arising from the partial reduction of the CGO electrolyte on the anode side, to be quantified. (C) 2003 Elsevier B.V. All rights reserved.
