Anode-supported solid oxide fuel cells with ion conductor infiltration

Abstract

Nano ion conductor infiltration to anode andcathode side of solid oxide fuel cell (SOFC) significantly improves the performance of an SOFC. The effects of processing parameters such as molar concentration, sintering temperature and holding time are investigated. The performance of fuel cell is evaluated with a test station and an impedance analyzer. The SEM investigation showed that a nano ion conductor phase forms around the main phase in the anode and the cathode. The results showed that nano infiltration enhances significantly the performance of SOFC. The power density is found to increase around two times with infiltration. It is also found that the particle size and the porosity significantly affect the performance of infiltrated SOFC cell. While smaller infiltrated grains enhance the performance lower porosity adversely affects the performance. Copyrightr (C) 2011 John Wiley & Sons, Ltd.
