Publication number: 20240093835Abstract: Heat is transferred from a first portion of liquid hydrogen to a flow of a heat transfer fluid at a first heat exchanger through heat exchange with a heat transfer fluid to produce a flow of vaporized hydrogen and a warmed flow of heat transfer fluid. The flow of vaporized hydrogen is combined with a second portion of liquid hydrogen in amounts designed to produce a combined flow with a desired temperature, the combined flow being used to fill one or more buffer vessels. Heat is also transferred at a second heat exchanger from a stream of pressurized hydrogen from the at least one buffer vessel to the cooled flow of heat transfer fluid to produce a cooled flow of pressurized hydrogen that is used to fill tanks of fuel cell electric vehicles.Type: ApplicationFiled: September 15, 2022Publication date: March 21, 2024Applicant: L'Air Liquide, Societe Anonyme pour l'Etude et l’Exploitation des Procedes Georges ClaudeInventors: Vincent FAIRY, Anh Thao THIEU, Samuel TROMPEZINSKI

Publication number: 20230295824Abstract: The invention relates to an apparatus for separating a product gas from an electrolysis medium, and for drying the product gas separated from the electrolysis medium. The apparatus includes a vessel, defining in its interior a liquid phase part and a gas phase part, whereby the liquid phase part and the gas phase part are immediately adjacent to each other, wherein the liquid phase part is configured to separate the product gas from the electrolysis medium loaded with product gas, to obtain a degassed electrolysis medium, and wherein the gas phase part is configured to dry the product gas separated from the electrolysis medium. The apparatus also includes an inlet for the supply of the electrolysis medium to the interior of the vessel, an outlet for discharging the degassed electrolysis medium from the vessel, and an outlet for discharging the separated product gas from the interior of the vessel.Type: ApplicationFiled: March 16, 2023Publication date: September 21, 2023Inventors: Olivier DEBELLEMANIERE, Nicolas RICHET, Anh Thao THIEU, Jorge Ernesto TOVAR RAMOS
