Abstract

L’invention porte sur un procédé de production d’hydrogène sous pression à une pression cible prédéfinie Pc par électrolyse de l’eau dite découplée, comportant une détermination (100) d’une valeur initiale Vc,0 du volume de gaz présent dans l’enceinte principale (2) au début d’une étape d’attaque ; une détermination (200) d’une valeur minimale mM,min de la quantité mM de métal M déposé ; puis la mise en œuvre (300) de l’étape de dépôt de sorte qu’une quantité mM de métal M au moins égale à la valeur minimale mM,min est déposée sur l’électrode négative (4) ; et la mise en œuvre (400) de l’étape d’attaque, le ciel gazeux présentant la valeur initiale Vc,0 déterminée et l’électrolyte (3) présentant le volume initial Ve,0, de sorte que l’oxydation de la quantité mM de métal M déposé entraîne la production d’hydrogène à une pression finale Pf au moins égale à la pression cible Pc. Figure pour l’abrégé : Fig. 1The invention relates to a process for producing hydrogen under pressure at a predefined target pressure Pc by electrolysis of so-called decoupled water, comprising a determination (100) of an initial value Vc,0 of the volume of gas present in the the main enclosure (2) at the start of an attack stage; a determination (200) of a minimum value mM,min of the quantity mM of metal M deposited; then implementing (300) the deposition step so that a quantity mM of metal M at least equal to the minimum value mM,min is deposited on the negative electrode (4); and the implementation (400) of the attack step, the gaseous sky having the determined initial value Vc,0 and the electrolyte (3) having the initial volume Ve,0, so that the oxidation of the quantity mM of metal M deposited results in the production of hydrogen at a final pressure Pf at least equal to the target pressure Pc.
