摘要： The invention concerns a fuel cell. The installation comprises cells consisting each of two anode sections (41, and 42), a connection between the first anode section output (91) and the second anode section input (82), a connection between the second anode section output (92) and the first anode section input (81), a circuit (10) supplying hydrogen to the anode circuits of the cells through two parallel connections (111 and 112) controlled by two opening-closing members (121 and 122), means for periodically controlling the inversion of states of the two members. The invention is applicable to air-hydrogen cells.

摘要： A reservoir is filled under pressure with a gas, by introducing a quantity of a gas into an intermediate receptacle (3), liquefying this quantity of gas, upon its introduction into the intermediate receptacle, by heat exchange with a refrigerant fluid, reheating and vaporizing this quantity of gas in the intermediate receptacle by thermal contact with a heat source (15), and placing in fluid communication the intermediate receptacle and the reservoir (2) when the pressure in the intermediate receptacle becomes greater than the pressure in the reservoir.

摘要： The carrier-borne VPSA system comprises at least one low-granulometric faujasite zeolite adsorber, whereby the Si/AI ratio ranges from 1 to 1.50 and the zeolite is exchanged with at least 10 % silver, and is also advantageously, highly exchanged with lithium. The invention can be used to supply the occupants of an aircraft with oxygen.

摘要： The invention relates to a method of supplying compressed air to at least a first and a second user station. According to the invention, an air flow is separated in a membrane-type unit (3) into a very slightly oxygen-depleted flow (5) which is used as the standard compressed air and an oxygen-enriched flow (4) which is typically diluted with the non-separated compressed air (10) in order to supply a user station (8) which exploits the oxidising nature of the compressed air. The invention can be used, for example, for the joint supply of combustion unit and compressed air supply lines.

摘要： The invention concerns a flow rate control system comprising two components (1, 2) made of materials with different expansion ratios, one of said components (7) being arranged at least partially around the first (1, 2) component so as to normally provide an annular outlet (13) which is closed when the component (7) contracts, the passage of the gas to be expanded being then limited to a passageway with reduced cross-section in the central component, for example consisting in an axial groove (12). The invention is useful for producing any type or Joule-Thomson effect cooler.

摘要： The invention concerns a method, wherein the gas is derived from a reaction unit (4) and comprises, as main constituents, essentially hydrogen and carbon monoxide. It consists, upstream of the permeation membrane unit (20), in purifying the gas mixture into secondary constituents contained in said mixture to contents less than 100 mole ppm, even to 1 mole ppm, and harmful by accumulation to the separating efficiency of the membrane unit. The invention is applicable to gas mixtures derived from installations (1) for reforming hydrocarbons with steam, for self-generated heat reforming, for CO2 reforming, for reforming or cracking methanol and/or partial oxidation of compounds containing carbon and hydrogen.
