Abstract

L'invention porte sur un compresseur d'hydrogène à hydrure métallique à fonctionnement continu, dans lequel il est prévu un chauffage/un refroidissement d'un hydrure métallique grâce à un système de pompe à chaleur. Le compresseur comprend au moins deux modules de compression, chacun d'eux comprenant un réservoir d'hydrure métallique comportant un lit d'hydrure métallique thermiquement couplé à un côté chauffage ou un côté refroidissement d'un système de pompe à chaleur, comprenant un côté chauffage, un côté refroidissement et un côté dissipateur thermique. Les réservoirs d'hydrure métallique sont aussi raccordés à un système de distribution de gaz, comprenant des tuyauteries pour l'introduction d'hydrogène basse pression et l'envoi en sortie d'hydrogène haute pression, des collecteurs de gaz, des clapets de non-retour et des tuyauteries de raccordement. En cours d'utilisation, le compresseur agit comme un système de pompe à chaleur réversible, où le côté chauffage et le côté refroidissement fonctionnent périodiquement et de façon alternée comme réchauffeur et comme refroidisseur. De ce fait, le lit d'hydrure métallique peut être chauffé à une température plus élevée, ce qui favorise une désorption de l'hydrogène haute pression qui s'y trouve, ou peut être refroidi à une température plus basse, ce qui favorise la pénétration, par absorption, d'hydrogène basse pression, par le même côté chauffage/refroidissement du système de pompe à chaleur, tout en éliminant en permanence du côté dissipateur thermique, à un niveau de température moyen, la chaleur excessive.
