Mathematics of the Electrochemical Extracton of Hydrogen from Iron.

Abstract

The transient current of hydrogen removal from iron following steady state permeation is analyzed theoretically for two limiting conditions at the i9nput side. For the fastest possible removal (C = 0 at X = 0 and at X = L), the amount extracted at the potentiostated side (X = L) is one third of the total present at steady state permeation described by Csub(X) - Csub(1 - X/L). Comparison of the integrated total flux and the amount given by the integral of Csub(X) indicates possible concentration dependence of hydrogen diffusivity in iron. (Author)
