Abstract

Empilage (10) de piles à combustible électrochimiques comprenant une série alignée de strates multifonctionnelles (panneaux) (30) placées de façon alternée entre une série correspondante de strates (12) électrochimiques actives. Dans un empilage de piles à combustible à membrane échangeuse de protons (PEM), les strates de piles à combustible électrochimiques comportent des strates d'ensembles électrodes à membrane (MEA). Les panneaux multifonctionnels servent à obtenir une intégrité structurelle et une continuité de circuit électrique à l'intérieur de l'empilage. Chaque strate multifonctionnelle comprend une couche conductrice (34) ouverte élastique, telle qu'une couche ondulée, prise en sandwich entre une paire de couches conductrices (32, 36) relativement rigides isolant la couche ouverte élastique des gaz réactifs. Les couches de la strate multifonctionnelle constituent ensemble un réseau élastique réparti exerçant une force de compression agissant dans la dimension de l'empilage, chaque couche ouverte élastique exerçant un effet de compression contre les couches conductrices rigides entre lesquelles elle est prise en sandwich. Le réseau élastique réparti permet de conserver l'intégrité dimensionnelle de l'intérieur de l'empilage grâce à un collecteur extérieur servant à alimenter l'empilage en gaz réactifs et à effectuer l'échappement de ces gaz. Les espaces situés entre les éléments élastiques ouverts servent de conduits d'air de refroidissement, de sorte que l'air de refroidissement peut s'écouler au-dessus des ondulations afin de refroidir l'empilage. Une structure de châssis simple et économique, les plaques de couverture associées et les barres de séparation de l'empilage de piles à combustible constituent et limitent un caisson de distribution séparé servant à alimenter les piles à combustible de l'empilage en gaz réactif et à opérer l'échappement de ces gaz.
