The target of this thesis was to study the feasibility of solid hydrogen storage in magnesium hydride (MgH2). At first, kinetic, thermodynamic and thermal properties of activated MgH2 powder have been investigated. Powders sorption kinetics are very sensitive to air exposure. The heat released by the very exothermic absorption reaction needs to be removed to load a tank with hydrogen in a reasonable time. In order to increase the thermal conductivity, a compression process of the material with expanded natural graphite (ENG) has been developed. Owing to that process, tough and drillable disks of MgH2 can be obtained with a reduced porosity and twice the volumetric storage capacity of the free powder bed. Handling those disks is easier and safer. Heat and mass transfer analysis has been carried out with a first small capacity tank (90 Nl), which is adapted to different experimental configurations. A second tank has been designed to fit disks of "MgH2 + ENG". This tank can absorbe 1200 Nl (105 g H. ) in 45 minutes, with a volumetric storage density equivalent to 480 bar compressed hydrogen. At the same time, a numerical modeling of MgH2 tanks has been achieved with Fluent® software. Numerical simulations of sorption process fit experiments and can be used for a better understanding of the storage material thermal and chemical behavior

Nowadays, the development of alternative energy sources becoming particularly important due to the effect of climate change and fossil fuels depletion. Hydrogen holds great promise thanks to its unlimited resources, high energy density, large technological flexibility and the environmentally friendly nature. With high potential of safety, storing hydrogen with metal hydrides (MH) is considered to be the optimal on-board hydrogen storage method for the future hydrogen vehicle. This thesis therefore contributes to analyzing the performance and proprieties of embedded MH hydrogen storage systems, including the characteristic estimation, dynamic modeling and thermal management coupling with fuel cells.Firstly, statistical models are proposed for dynamic performance analysis and state of charge (SOC) calculation. The online SOC estimation process is then realized combining a multi-joint state classifier. The dynamic model of the embedded MH tank considering mass and energy conversion is proposed using optimized parameters identified through particle swarm optimization (PSO) algorithm. Moreover, the dynamic behavior of the fuel cell system integrating proton-exchange-membrane fuel cell (PEMFC) and MH hydrogen storage tank is simulated with a mathematical model set and validated using a database from the real operation vehicles. A thermal management strategy with PID controller is proposed to reduce the degradation and extend the lifespan of PEMFC. Finally, a test bench is designed in laboratory and experiments are carried out to validate the proposed models and strategies

A study of the hydrogen storage using metal hydride is presented. We use the energy equation to analyze the associated heat transfer problem based on assuming that thermal equilibrium has been reached between the metal hydride and hydrogen gas. The mass balance between the hydrogen gas and metal hydride is described in terms of the continuity equation. The Forchheimer-Brinkman equation is used to describe the gas flow within the porous medium . The mathematical model developed was solved using a finite volume method, FLUENT6.3 (Fluent, Inc. USA). The effect of bulk diffusion is considered for mass transfer in the solid phase. Temporal and spatial variations of temperature and concentration in hydride bed are plotted. Emphasis is given to monitor the motion of hydrogen within the bed and to the influence of the L/D ratio and porosity. It is observed that a concentration variation in the bed is the driving force for hydrogen flow in hydride beds. The gas movement is observed to be from saturated cooler peripheral region towards the unsaturated hotter core region of the bed.

A study of the hydrogen storage and usage using LaNi5 metal hydride is presented. The metal hydride tank is considered to consist of a porous medium (hydride bed) and an expansion volume (gaseous phase). For this storage structure a mathematical model including both hydriding and dehydriding processes is developed. When metal hydrides absorb hydrogen, they release heat. Conversely, when they absorb heat, the alloys release hydrogen. Therefore we use the energy equation to analyze the associated heat transfer problem based on assuming that thermal equilibrium has been reached between the metal hydride and hydrogen gas. The mass balance between the hydrogen gas and metal hydride is described in terms of the continuous equation. The Forchheimer-Brinkman and Navier-Stokes equations are used to describe the gas flow within the porous medium and expansion volumes respectively. The mathematical model developed was solved using a finite element code, COMSOL Multiphysics 3.2 (COMSOL Inc., Sweden). Results show during the process of either absorbing or releasing hydrogen, the inside flow influenced by the fact that the temperature profile is not uniform in the tank has a major impact on the changes of the gas density. Hydride absorption or desorption both take place faster neat the tank wall because there is better heat exchange near the wall. Using the simulation model, we also study how the hydrogen reaction rates change with the parametric values. Result show changing the external cooling/heating temperature or the inlet/outlet gas pressure has profound influences on the hydriding and dehydriding speeds. In contrast, the inlet diameter and expansion height have virtually nothing to do with the hydriding and dehydriding rates.
