Abstract
To evaluate the influence of SOFC electrode microstructure on electrochemical reaction at the surface of electrode, focused ion beam fabrication and scanning electron microscope combined dual-beam system (FIB-SEM) is used for taking the microstructure data into account for numerical analysis to consider the gas and electrochemical reaction distribution in the electrode. As a result, it is found that the small amount of electrode was not worked as a reactive surface because that kind of domain was not connected to the other particles or reactive fuel is not distributed to reactive domain.
