Experimental and theoretical study of a metal-hydrogen reactor

An experimental and theoretical study of a metal-hydrogen reactor (LaNi5-H-2) is presented. The first goal of this study is to experimentally determine the effective thermal conductivity, the conductance between the hydride bed and the fluid around the reactor, the equilibrium pressure and the expression of the reaction kinetics, taking into account the initial condition, the temperature and the applied hydrogen pressure temporal evolution. The second goal is to test the validity of the theoretical model by comparison between theoretical and experimental results. (C) 1999 International Assocation for Hydrogen Energy.
