연료전지용 밸브의 내환경 평가 방안에 관한 연구

The work fluid in the fuel cell is explosible gas. Thus, the component that used in the fuel cell is needed a high reliability for the wrong operation protection. Usually the durability test is used to confirm the reliability for this component. However, this durability test can guarantee of the machinery damage that was come from the repetitive operation. it can not guarantee of the thermal damage when surrounding temperature was changed. This study tries to confirm the reliability of the thermal damage in the substitution preventing valve with environmental test.
