Abstract

　L'invention concerne un système de fourniture d'hydrogène pour fournir de l'hydrogène, le système de fourniture d'hydrogène étant pourvu d'une unité de réaction de déshydrogénation, pour obtenir un gaz contenant de l'hydrogène par déshydrogénation d'un matériau de départ comprenant un hydrure d'un hydrocarbure aromatique, d'une unité de purification d'hydrogène, pour éliminer un produit de déshydrogénation du gaz contenant de l'hydrogène obtenu par l'unité de réaction de déshydrogénation et obtenir un gaz purifié comprenant de l'hydrogène de haute pureté, d'une unité de compression, pour placer le gaz purifié obtenu par l'unité de purification d'hydrogène sous haute pression, et d'une unité de détection pour détecter la teneur en hydrocarbure incluse dans le gaz purifié dirigé depuis l'unité de purification d'hydrogène vers l'unité de compression.
