Abstract

Theconstant potential and constant current discharge techniques were used todetermine the hydrogen diffusion coefficients in an LaNi_4.25Al_0.75 electrode. The valuesobtained were 2.97 × 10^–11 and 3.30 × 10^–11 cm²/s, respectively. The advantages and disadvantages of these two techniques are discussed.
