A device includes a catalytic system and an electromagnetic system. The catalytic system defines a catalysis chamber and includes a catalyst of a reaction to generate a gas from a liquid. The catalyst is housed in the catalysis chamber. The electromagnetic system includes a coil and a rod mobile relative to the coil, the rod being fixed to the catalytic system and including a magnet and a core. The electromagnetic system is configured to move the rod relative to the coil when an electrical current is passed through the coil, so as to dispose the catalytic system in an open position in which the catalysis chamber is in fluidic communication with the outside. The catalytic system is disposed in a closed position in which the catalysis chamber is hermetically closed in the absence of an electrical current through the coil.

A catalytic device includes a hollow body, a piston housed in the hollow body, a catalyst of a gas generation reaction based on bringing a reactive liquid into contact with the catalyst, the catalyst being housed in a catalysis chamber, the piston and the hollow body defining a hermetic compression chamber for containing a compressible fluid, and being mobile relative to one another between a closed position in which the catalysis chamber is tight to the reactive liquid, and an open position for the entry of the reactive liquid into the catalysis chamber. The catalytic device is conformed to switch from the open position to the closed position, respectively from the closed position to the open position, when the compressible fluid is contained in the compression chamber and a force applied to the piston is greater than or equal to, respectively less than, a closure force.
