(Invited) On Degradation Mechanisms of Ni-YSZ Fuel Electrodes in Solid Oxide Cells
View through CrossRef
This is a continuation of a series of articles by the principal author on degradation of Ni-YSZ cermet electrodes. This one gives a brief listing of the main aspects and in particular of the disagreements in literature on the long term degradation mechanisms of Ni-YSZ electrodes at high current density. Two main hypotheses are presented, and the weaknesses and strengths are briefly discussed. Recommendations for alleviation of the degradation are given as well as for needed experiments in the future.
