LIQUID HYDROGEN PRESSURIZING AND REFUELING SYSTEM COOPERATIVELY DRIVEN BY WORK AND HEAT

A liquid hydrogen pressurizing and refueling system cooperatively driven by work and heat, which takes a cascaded low-temperature high-pressure container group as a system core, uses a combined mode of pressurization by a reciprocating liquid hydrogen pump (4) and isochoric heat pressurization by low-temperature high-pressure containers (6), thereby achieving staged pressurization of liquid hydrogen to 80-100 MPa, and uses the cascaded low-temperature high-pressure container group to refuel a vehicle-mounted storage tank (18). The pressurization process and the refueling process are deeply coupled, a hydrogen flow in the refueling process is used as a heat transfer medium, and efficient in-tank heat pressurization of the low-temperature high-pressure containers (6) is achieved without the need for an extra driving force. L'invention concerne un système de pressurisation et de ravitaillement en hydrogène liquide entraîné en coopération par le travail et la chaleur, qui prend un groupe de réservoirs haute press
