A fuel battery used by being mounted on a portable small-sized electric device, comprising a thin type substantially rectangular parallelepiped box (2), in which installed are a cell section (1) consisting of one or more fuel cells (14), a fuel tank section (3) for storing fuel that is to be fed to the cell section (1), and a fuel feed section (4) for feeding fuel in the fuel tank section (3) to the cell section (1), and openings (7) for feeding an oxidant gas to the cell section (1), wherein the fuel tank section (3), fuel feed section (4), and cell section (1) are disposed between the two opposed short-side surfaces (83a, 83b) of the box (2) in one direction. Such arrangement provides a large-capacity, high-output, small-sized fuel battery.
La présente invention concerne une pile à combustible convenant au montage et à l'utilisation sur un dispositif électrique de petites dimensions. Cette pile à combustible tient dans un carter plat sensiblement parallélépipédique rectangle (2). Le carter abrite un module cellulaire (1) d'au moins une cellule à combustible (14), un module réservoir (3) pour le combustible alimentant le module cellulaire (1), et un module d'alimentation (4) faisant passer le combustible du réservoir (3) au module cellulaire (1). Des orifices (7) permettent d'entrée de gaz oxydant dans le module cellulaire (1). Les trois modules (3, 4, 1) sont alignés entre les deux petites faces opposées (83a, 83b) du carter (2). Cet agencement permet la réalisation d'une pile à combustible se distinguant par sa grande capacité, son débit élevé et ses petites dimensions.
