Abstract

L'invention concerne un accumulateur oxyde de métal/hydrogène clos et étanche aux gaz ayant une électrode positive qui comprend un oxyde de métal, une électrode négative qui comprend un alliage stockant l'hydrogène, un séparateur agencé entre les électrodes positive et négative qui contient un électrolyte alcalin, ainsi que des moyens pour la recombinaison catalytique de l'oxygène développé lors d'une surcharge sur l'électrode positive. Selon l'invention, pour la protection de l'électrode négative (1) vis-à-vis de l'oxygène qui arrive, les particules d'hydrure de métal possèdent un enrobage (6) en un métal qui a une fable affinité pour l'oxygène mais par contre qui présente un fort pouvoir d'absorption vis-à-vis de l'hydrogène et les moyens maintenant l'utilisation de l'oxygène sont agencés en dehors du trajets des ions entre les électrodes positive (2) et négative (1) mais cependant en contact électriquement conducteur avec l'électrode négative. L'invention s'applique notamment aux batteries d'accumulateurs.
