Description

The objective of this thesis is the energy optimization of the micro-cogeneration and micro-trigeneration fuel cell system. First, a mathematical modeling of all the components of the fuel cell cogeneration system was conducted. The influence of several parameters such as pressure and current density on micro-CHP system performance is examined. The energy and environmental relevance of the system for the French context is studied. Then, a numerical study of a tri-generation system consisting of a fuel cell and a single-acting H2O/Li-Br absorption machine was conducted. The micro-trigeneration unit is coupled to a single-family house and the energy performance of the system is evaluated. Finally, in order to evaluate the potential of coupling the tri-generation system with renewable energies, a hydrogen production system with photovoltaic panels 'PV-H2' has been studied. A modeling of the various components of the 'PV-H2' system has been carried out. The simulation results of the coupling of the 'PV-H2' system with an individual house in the eco-district of La Glacerie are presented. (author)

Abstract (French)

L'objectif de cette these est l'optimisation energetique d'un systeme de micro-cogeneration et micro-tri-generation a pile a combustible. Dans un premier temps, une modelisation mathematique de tous les composants du systeme de cogeneration a pile a combustible a ete menee. L'influence de plusieurs parametres tels que la pression et la densite de courant sur les performances de systeme microcogeneration est examinee. La pertinence energetique et environnementale du systeme propose pour le contexte francais est etudiee. Ensuite, une etude numerique d'un systeme de tri-generation compose d'une pile a combustible et d'une machine a absorption simple effet H2O/Li-Br a ete menee. L'unite de micro-tri generation est couplee a une maison unifamiliale et la performance energetique du systeme est evaluee. Enfin, afin d'evaluer le potentiel de coupler le systeme de micro-tri-generation avec les energies renouvelables, un systeme de production d'hydrogene avec les panneaux photovoltaiques 'PV-H2' a ete etudie. Une modelisation des differents composants du systeme 'PV-H2' a ete realisee. Les resultats de simulation du couplage du systeme PV-H2 avec une maison individuelle de l'eco-quartier de la Glacerie sont presentes. (auteur)
