Abstract

La présente invention concerne une pile à combustible avec oxyde solide, divisée de façon à empêcher un contact défectueux avec une plaque de séparateur supérieure lors de la stratification de la plaque de séparateur, et permettre ainsi un recueil de courant lissé. L'invention comprend : une pile unique comprenant un électrolyte, et une électrode à combustible (anode) et une électrode à air (cathode) respectivement formées sur les deux côtés de l'électrolyte ; et un élément d'amortissement souple joint à la pile unique. En conséquence, il est possible d'empêcher un contact défectueux avec la plaque de séparateur supérieure, et ainsi d'assurer un recueil de courant lissé puisque la surface de la pile assemblée sur la plaque de séparateur est complètement placée en contact étroit avec la plaque de séparateur supérieure grâce à l'élément d'amortissement lors de la stratification de la plaque de séparateur.
