Summary

In this paper, the pore structure characteristics of two considerably different ceramic electrode materials were successfully investigated using flow porometry. Through pore throat diameters, distribution of flow rate over pore diameters and gas permeability were measured. Pore volumes measured with mercury intrusion porosimetry showed that the through pores and the blind pores were associated with considerable volume of wide parts. The results were consistent with scanning electron micrographs.
