Electrochemical performance of 3DOM anode-supported SOFC fed with 13A gas

Abstract

The electrochemical performance of three-dimensionally ordered macroporous (3DOM) anode-supported SOFC was investigated by feeding 13A gas. At 700 ° C, the cell with 3DOM anode (3DOM-type) showed 1.3 times higher power density than that with random-structured anode (conventional-type). Furthermore, the polarization resistance of 3DOM-type cell was low compared with the conventional-type cell at low current densities. This result suggests that reforming reactions of 13A gas were promoted in 3DOM anode.
