Abstract: The present invention relates to a device (10) for storing and restoring electrical energy comprising a chamber (100) in which water electrolysis means (110), a fuel cell (120), and monitoring/control means (130) for monitoring the operation of said device (10) in the fuel cell mode or the electrolyzer mode are arranged. Connection means (141) enable said chamber (110) to be connected to storage means (210) for storing dihydrogen (H2), which are outside of said chamber (110).

Abstract: A device generating hydrogen from a hydrocarbon, oxygen and water. The reaction is carried out at high temperature. The device includes a first substantially cylindrical zone surrounding the reaction chamber circulates water vapor and hydrocarbon, excluding the reaction products, the zone being separated from the reaction chamber to recover heat lost by the reaction chamber, to preheat the mixture circulating in the first zone. The reagent(s) are in contact with the walls of said first zone to exchange produce heat. A substantially cylindrical second zone surrounds the first zone and circulates water to be vaporized, the water is in contact with the walls of said second zone. The first and second zones are separated such that water circulating in the second zone is preheated by heat of the first zone where the water of the second zone is mixed with the hydrocarbon and introduced into the first zone.
