A method for treating a polymer part comprising a step of bringing the part into contact with vapours of solvent(s), capable of at least partially solubilising the part, this contacting step being carried out under vacuum. Application of this method for modifying the roughness of the part and/or functionalising it.

Method for treating a polymer part in order to modify its roughness and/or to functionalise it

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.

Device for generation of a gas

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.

Gas generation device

Disclosed herein is a gas generator that contains a liquid reactant that reacts to produce a gas in the presence of a catalyst. The catalyst is contained in a carrier that is buoyant in the liquid reactant. The gas generator also has at least one carrier movement restraining member adapted to selectively control the location of the carrier, and at least one compressible body containing a volume of gas. In a first configuration, when an internal pressure of the gas generator is lower than an internal pressure of the compressible body, the compressible body increases in volume, and in a second configuration when the internal pressure of the gas generator is higher than the internal pressure of the compressible body, the compressible body decreases in volume. The carrier movement restraining member restricts the carrier's movement in the first configuration.

The invention relates to an ion/electron-conducting composite polymer membrane ('), which comprises at least two gas-tight ion-conducting polymer portions (&#x2032;) joined together directly by a gas-tight electron-conducting polymer portion (&#x2032;). It also relates to processes that enable this membrane to be manufactured, and also to a planar fuel cell core comprising it. Applications: production of planar fuel cells used for generating electrical power intended for stationary applications, transport applications and portable and transportable applications.
