  • There is a rapid performance degradation in the initial aging process of solid oxide fuel cell (SOFC), and the discussion of degradation mechanism needs quantitative analysis. The Focused Ion Beam - Scanning Electron Microscopy (FIB-SEM) technique is used to characterize and reconstruct the ceramic microstructures of SOFC anodes. The lattice Boltzmann method (LBM) simulation is performed to simulate the multi-physical and electrochemical processes in the reconstructed models. Two samples taken from industrial size cells are processed, including a reduced reference cell, and a cell with an initial aging process. Statistical parameters of the reconstructed microstructure show a significant decrease in the active triple-phase boundary (TPB) and Ni connectivity in the aged cell compared to the reference cell. The LBM simulation reveals that the activity degradation is the dominant factor compared to the microstructure degradation during the initial aging process, and the electrochemical reactions spread to the support layer in the aged cell. The microstructure degradation and activity degradation can both be attributed to the Ni migration and coarsening.
