Publication number: 20230151929Abstract: The present invention relates to a method for improving stability of a hydrogen gaseous dispensing system. An example of such system is hydrogen powered vehicle fuel filling station. Vehicle is filled by multiple high pressure gaseous hydrogen tubes, usually one tube at a time. For safety and reliability reasons a control requirement for such system is to be able to deliver the hydrogen at constant rate to the fuel tank so that its rate of pressure increase stays constant during entire filling process. A dual pressure regulator arrangement is proposed to better maintain flow continuity and/or pressure during tube switching.Type: ApplicationFiled: November 16, 2021Publication date: May 18, 2023Applicant: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Pierre-Philippe GUERIF, Paul KONG, Wendy May Yee YIP, Aaron HARRIS, Jorge LOPEZ
