A binary gas permeation method is proposed to investigate the gas transportation characteristics of the components of solid oxide fuel cells. The properties of porous media, such as pore diameter, porosity and tortuosity factor, are obtained from the measured permeabilities for two different gases in this method. It is also confirmed experimentally that the permeabilities are predicted with a good accuracy for other gases as well as for nonisobaric binary gas diffusion systems. Moreover, we refer to the airtightness of plasma-sprayed yttria-stabilised zirconia films, and estimate the concentration polarization and the distribution of total pressure in porous media at a high temperature.
