In this study, stationary polarisation curves were obtained for a porous nickel electrode under varying temperatures and anode gas compositions. The exchange current densities were determined from the slopes of the polarisation curves at low overpotentials, i.e. the assumption was made that the porous electrode is under kinetic control. The outlet gas compositions were measured by analysis in a gas chromatograph. The gases were found to be far from equilibrium. However, almost the same reaction orders were found independently of the assumptions of gas compositions but they were rather high and therefore difficult to explain by the generally assumed mechanisms.
