抄録

In the multi-scale analysis of oxygen potential distributions in Solid Oxide Fuel Cell (SOFC), the evolution of the microstructure in anode is reflected in the macroscopic electrical conductivities and the amount of triple-phase boundaries which are the generation sites of electro-chemical reaction currents. The oxygen potential distributions induce the reduction strains in oxide materials along with the thermal strains due to temperature change. These strains cause the macroscopic deformation in mutually constrained components. The capability of the proposed method is demonstrated in characterizing the aging degradation of the macroscopic electro-chemo-mechanical behaviour of SOFC that is caused by the Nisintering in anode microstructures during long-period control.
