Abstract: A device for generating gas by placing a liquid reactant in contact with a solid element, including: a liquid reactant tank, a reaction chamber configured to contain the solid element, an injector configured to inject the liquid reactant onto the solid element, and an outlet port configured to collect the gas generated in the reaction chamber, wherein the tank and the reaction chamber are separated in a sealed manner by a mobile wall, the mobile wall including an outlet port for collecting the gas generated in the reaction chamber, and wherein the injector passes through the mobile wall and configured to move into the solid element.

Abstract: Device for generating gas by placing a liquid reactant in contact with a solid element, comprising a liquid reactant tank (6) and a reaction chamber (8) intended to contain the solid element, wherein the tank (6) and the reaction chamber (8) are separated in a sealed manner by a mobile wall (4), with an outlet port (26) for collecting the gas generated in the reaction chamber and means (14) for injecting the liquid reactant onto the solid element, which injection means (14) pass through the mobile wall (4) and are capable of moving into the solid element.

Abstract: An alkaline fuel cell comprises at least one electrolyte having an anode disposed thereon. The anode is formed by a stack of a first thin layer and a second thin layer disposed between the electrolyte and the first thin layer. The first thin layer consists of aluminium or an aluminium alloy whereas the second thin layer preferably consists of zinc or a zinc alloy. The anode of the alkaline fuel cell is preferably produced by depositing the second thin layer designed to come into contact with the electrolyte, by physical vapor deposition, on a substrate formed by the aluminium or aluminium alloy first thin layer.
