Features of Chronoamperometric Studies of Water Sorbent Materials

Keywords

MH electrode, сonstant potential discharge, hydrogen diffusion coefficient

Abstract

The present study examines the constant potential discharge method at –0.6 V (CPD) for three different hydrogen absorbing materials: nano-Ni-C synthesized from polystyrene and metal salts using the pyrolysis method; Ni-Raney obtained through leaching, and La3MgNi14 alloy are prepared by sintering and prolonged heat treatment. Each of the samples corresponds to distinct time domains (according to the theory of the method under consideration), indicating different mechanisms diffusion and hydrogen diffusion coefficients.
