Abstract
An electrochemical method based on the limiting current measurement has been proposed for measuring the hydrogen permeability through metal membrane. In this method, the hydrogen permeability can be obtained directly from the limiting current measurement, if the diffusion through the metal is the rate-limiting process of the hydrogen permeation. Based on this concept, an electrochemical device has been developed and applied to the measurement of the hydrogen permeability of pure palladium and V-15Â mol% Ni alloy at high temperature up to 673Â K. It is shown that the measured hydrogen permeability through pure palladium and V-Ni alloy are in good agreement with the previous works.
