Electrochemical Determination of the Diffusion-Coefficient of Hydrogen Through an Lani4.25Al0.75 Electrode in Alkaline Aqueous-Solution
The constant potential and constant current discharge techniques were used to determine the hydrogen diffusion coefficients in an LaNi4.25Al0.75 electrode. The values obtained were 2.97 x 10(-11) and 3.30 x 10(-11) Cm-2/s, respectively. The advantages and disadvantages of these two techniques are discussed.
