Abstract
The activation energy for the removal of surface carbon formed by meth ane decomposition following high-temperature reforming, from a nickel/ zirconia solid oxide fuel cell (SOFC) anode has been calculated using two methods based on temperature-programmed oxidation. It is found tha t the re is a fairly good agreement between the two methods. In additi on, it was observed that the addition of small quantities of lithium t o the anode resulted in a significant lowering of the activation energ y for surface carbon removal by about 50 kJ mol(-1).
