摘要：

A two-compartment reactor separated by a palladinized Pd sheet electrode was used in a new dehydrogenation system which was constructed by combining dehydrogenation of formic acid without dilution at one side of the palladinized Pd sheet electrode with electrochemical oxidation of permeated atomic hydrogen at another side. The increase in oxidation current demonstrated that the dehydrogenation system proceeded successfully. From a theoretical analysis of time course of the oxidation current for the palladinized Pd sheet electrode, the diffusion coefficient of hydrogen was evaluated, and its Arrhenius plot was drawn for determining an activation energy for the diffusion of hydrogen. These values were in good agreement with the previously evaluated ones, suggesting that the permeation process of atomic hydrogen through the palladinized Pd sheet electrode was rate determining.
