| description | A purification system and method for purifying a hydrogen stream supplied from a storage tank mounted in a vehicle to produce a purified hydrogen stream for use in a PEM fuel cell system that is utilized within the vehicle. The hydrogen is purified within a membrane separator having hydrogen transport membrane elements having a dense metallic layer such as palladium to separate the hydrogen from the impurities. The separated hydrogen is supplied to the PEM fuel cell. In order to heat the membrane to its operational temperature, heat is recovered from the hydrogen permeate stream of the membrane system in a first heat exchanger and heat is generated by combusting the retentate stream containing residual hydrogen and impurities.
La présente invention concerne un système et un procédé de purification destinés à purifier un courant d'hydrogène alimenté d'un réservoir de stockage monté dans un véhicule pour produire un courant d'hydrogène purifié destiné à être utilisé dans un système de pile à combustible PEM qui est utilisé à l'intérieur du véhicule. L'hydrogène est purifié à l'intérieur d'un séparateur à membranes ayant des éléments de membranes de transport d'hydrogène ayant une couche métallique dense telle que du palladium pour séparer l'hydrogène des impuretés. L'hydrogène séparé est alimenté à la pile à combustible PEM. De manière à chauffer la membrane à sa température opérationnelle, la chaleur est récupérée du courant de perméat d'hydrogène du système à membranes dans un premier échangeur thermique, et de la chaleur est générée par combustion du courant de rétentat contenant de l'hydrogène résiduel et des impuretés. |
