Title (EN) COMPACT MULTI-FUNCTIONAL MODULES FOR A DIRECT METHANOL FUEL CELL SYSTEM
(FR) MODULES MULTIFONCTIONNELS COMPACTS POUR SYSTEME DE PILE A COMBUSTIBLE AU METHANOL DIRECT
Abstract:
(EN) A compact direct methanol fuel cell (DMFC) system based on modules is provided. The system addresses issues related to the critical functions of water recovery from the cathode exhaust, carbon dioxide separation from the anode output stream, dilution of incoming concentrated methanol and thermal management in a DMFC system. The system is based on a more natural solution and avoids bulky and power-consuming devices; hence increasing DMFC system's efficiency by at least 25%, reducing DMFC system's cost and increasing DMFC system's reliability compared to traditional condensor-based DMFC systems. In addition, the system is relatively small in size compared to these condensor-based DMFC systems mainly due to the use of modules based on plates that are nicely integrated as a DMFC system. The individual size of the system is typically reduced by about 35% or more compared to traditional condensor-based DMFC systems.
(FR) L'invention concerne un système de pile à combustible au méthanol direct (DMFC) compact à base de modules. Ledit système permet de résoudre les problèmes associés aux fonctions critiques de récupération d'eau des gaz d'échappement de la cathode, de séparation du dioxyde de carbone du flux de sortie de l'anode, de dilution de méthanol concentré entrant et de gestion thermique dans un système DMFC. Le système est basé sur une solution plus naturelle et évite l'utilisation de dispositifs consommateurs d'énergie et volumineux ; augmentant ainsi l'efficacité du système DMFC d'au moins 25 %, réduisant le coût du système DMFC et augmentant la fiabilité du système DMFC, comparé à des systèmes DMFC à base de condensateurs. De plus, le système présente une taille relativement petite, comparé aux systèmes DMFC à base de condensateurs, principalement due à l'utilisation de modules à base de plaques qui sont parfaitement intégrés en tant que système DMFC. La taille individuelle du système est généralement réduite d'environ 35 % ou plus comparé aux systèmes DMFC à base de condensateurs.
