A hydrogen gas cooled hydrogen storage element which includes a hydrogen storage alloy material in which hydrogen flow channels are provided. The flow channels provide pathways through the hydrogen storage material to allow for high speed hydrogen gas flow. A portion of the high speed hydrogen flow is stored within the storage material which releases its heat of hydride formation. The remainder of the hydrogen flows through the hydrogen storage material at a sufficient mass flow rate to remove the heat of hydride formation. The unit includes a casing (1), which houses the storage coil (2). The storage coil is composed of a spirally wound hydrogen storage alloy belt (3). The flow channel material (4) allows for flow of the high flow rate hydrogen through the storage unit.

Elément de stockage d'hydrogène refroidi par de l'hydrogène gazeux et comprenant un matériau d'alliage de stockage d'hydrogène comportant des canaux d'écoulement d'hydrogène. Ces canaux constituent des trajets à travers le matériau de stockage d'hydrogène, ce qui permet à l'hydrogène gazeux de circuler rapidement. Une partie de cet hydrogène à circulation rapide est stockée à l'intérieur du matériau de stockage qui dégage sa chaleur de formation d'hydrure. Le reste de l'hydrogène s'écoule à travers le matériau de stockage d'hydrogène à un débit massique suffisant pour supprimer la chaleur de formation d'hydrure. Ce dispositif comprend un boîtier (1) logeant une bobine de stockage (2). Cette dernière est composée d'une bande (3) en alliage de stockage d'hydrogène enroulée en spirale. Le matériau (4) des canaux d'écoulement permet à l'hydrogène de débit rapide de s'écouler à travers ce dispositif de stockage.
