摘要：

Values of the self-diffusion coefficients for sodium and cesium ions in 1200 Equivalent Weight Nafion® membranes have been deduced from conductivity measurements, assuming the validity of the Einstein relation between self-diffusion coefficient and absolute ionic mobility. Results obtained are in good agreement with previously published data obtained from direct measurements. © 1990.
