In this paper we investigate the oscillatory response of a methane fuelled solid oxide fuel cell (SOFC) under weakly humidified conditions. We present experimental results conducted using operating conditions which allow for direct comparison with the mathematical model presented in Sands et al. 2014. We find transitions from a stable, steady current producing state, to nonlinear autonomous oscillations, to a zero current output state, which corresponds to the pattern of behavior also observed in the model. In this paper we briefly summarize the model from Sands et al. 2014, followed by a description of the cell assembly and experimental procedures. The results are then presented, followed by a discussion and comparison with the model. (C) 2016 The Electrochemical Society. All rights reserved.
