STRUCTURE OF HYDROGEN SUPPLY CHAMBER USING MULTI-EJECTOR AND HYDROGEN SUPPLY ASSEMBLY COMPRISING THE SAME

摘要

PURPOSE: A structure of hydrogen supply chamber using a multi-ejector is provided to reduce the volume due to the simplification of configuration and production costs, to ensure high reliability, and to improve fuel efficiency and stack durability of fuel cell vehicles. CONSTITUTION: A structure(130) of hydrogen supply chamber using a multi-ejector(120) comprises: an injection channel(133) through which hydrogen gas flows in; a first chamber(131) communicating with a first ejector(121) by being connected to the inflow path; at least one auxiliary chamber(132) communicating with a corresponding ejector by being connected to the first chamber; and at least one mechanical valve(137) configured to be opened and closed according to pressure variation within the first chamber or the auxiliary chamber.
