Abstract

The invention relates to a hydrogen supply apparatus. The apparatus includes a first connecting member having a first flow path through which hydrogen is supplied and a second connecting member connected to the first connecting member and having a second flow path that communicates with the first flow path. A back-up ring has a first packing portion abutting an inner surface of the first connecting member, a second packing portion abutting an outer surface of the second connecting member, and a connecting portion connecting ends of the first packing portion and the second packing portion. An elastic member is elastically compressible and expandable between the first and second packing portions.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2020-0025779 filed on March 2, 2020, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to a hydrogen supply device and a sealing device for the hydrogen supply device, and more particularly, to a hydrogen supply device capable of improving sealing performance, safety and reliability and a sealing device for the hydrogen supply device device. Background technique [0004] A fuel cell electric vehicle (FCEV) generates electricity through an electrochemical reaction between oxygen and hydrogen in a fuel cell stack and uses the electricity as a power source. Regardless of battery capacity, fuel cell electric vehicles can continuously generate electricity by supplying fuel and air from the outside, so they are highly efficient and emit almost no pollutants. Due to these advantages, resear...
