Abstract: A device for generating a gas by putting a liquid into contact with a catalyst includes an enclosure defining a first chamber for containing the liquid and a second chamber for containing the catalyst. A valve member is mounted to move inside the enclosure between a closed position in which the first chamber and the second chamber are isolated from each other and an open position in which the first chamber and the second chamber are in fluid-flow communication. Accordingly, the valve member is connected to an elastically-deformable diaphragm forming a wall of the enclosure. The diaphragm is coupled to an actuator arranged outside the enclosure to deform said diaphragm in such a manner as to move the valve member between the closed position and the open position.
