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