| 英文摘要 | a novel method for measuring effective diffusion coefficient of porous materials is developed. the oxygen concentration gradient is established by an air-breathing proton exchange membrane fuel cell (pemfc). the porous sample is set in a sample holder located in the cathode plate of the pemfc. at a given oxygen flux, the effective diffusion coefficients are related to the difference of oxygen concentration across the samples, which can be correlated with the differences of the output voltage of the pemfc with and without inserting the sample in the cathode plate. compared to the conventional electrical conductivity method, this method is more reliable for measuring non-wetting samples.
