 note = {The following three electrochemical hydrogen permeation methods; (1) Hydrogen permeation current method (2) Hydrogen potential method, (3) Current pulsehydrogen potential method have been compared in order to determine the exact diffusion coefficient of hydrogen in both annealed and as cold rolled Pd at room temperature, especially in view of the fitness of observed permeation transient with theoretically predicted one. The experimental permeation transients obtained by the hydrogen permeation current method with galvanostatic charging for both Pd specimens were fitted better to the theoretical curve derived under the constant hydrogen concentration directly beneath the cathodic surface than the theoretical curve obtained under the constant hydrogen flux charged at the cathodic surface, regardless with the cathodic current densities. On the other hand, both the hydrogen potential and the current pulsehydrogen potential methods under galvanostatic charging did not show the close fitness between the experimental transients and theoretical one. The method of determination of the hydrogen diffusivity and concentration of hydrogen by using the relation of log (√t ・Jt) vs. 1/t from the permeation transient obtained by the hydrogen permeation current method is the most useful for the simplicity and the precision of data handling., 長崎大学工学部研究報告, (18), pp.79-88; 1982},
