摘要: Abstract A RedOx cycle is one of the most dangerous factors anode degradation due to microstructure changes. In this paper, evolution during a caused by fuel starvation process was studied using electrochemical measurements. After power generation experiment, reconstructed combination focused ion beam and scanning electron microscopy (FIB–SEM). The changes were quantified for parameters such as tortuosity factor, tripe phase boundary density, volume fraction, connectivity average grain size. three dimensional reconstruction indicated that condition might cause significant in morphology.
