Problems solved by technology

[0010] We have found that if air is introduced into the fuel cell stack when the vehicle is not used for an extended period of time (e.g. parked for a long period of time), the fuel cell stack can degrade, which can lead to reduced performance of the fuel cell stack

Abstract

An air control valve for a fuel cell vehicle includes: a valve housing in which an air flow path is formed; a valve member configured to selectively open or close the air flow path; and a driving unit configured to linearly operate the valve member such that the valve member linearly moves from a first position closing the air flow path to a second position opening the air flow path, whereby a beneficial effect of improving sealing performance and improving stability and reliability may be obtained.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2020-0137426 filed on October 22, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an air control valve for a fuel cell vehicle capable of improving sealing performance and preventing deterioration of a fuel cell stack. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] A fuel cell system refers to a system that continuously generates electrical energy through a chemical reaction of continuously supplied fuel. As an alternative capable of solving global environmental problems, research and development on fuel cell systems has been ongoing. [0006] Based on the type of electrolyte used in the fuel cell system, the fuel cell system c...
