초록

다양한 고무 충전제가 연료전지 스택용 가스켓의 재료로서의 적합성 및 스택체결에 있어 미치는 영향을 살펴보기 위하여, 카본블랙 및 실리카계 충전제를 사용하여 고무를 배합하였다. 이렇게 배합된 고무재료를 PEMFC (polymer electrolyte membrane fuel cell)의 구동환경을 고려하여 열과 상대유에 대한 장기평가를 실시하였다. 가스켓에 가장 요구되는 압축 영구 줄음율은, 1000 h까지의 장기평가에서도 15% 이하의 우수한 특성을 보였다. 다양한 충전제를 사용한 배합한 고무재료로 가스켓을 제작하고, 체결시 가스켓과 가스켓 사이의 밀봉력을 FEM (finite element method)을 실시하여 최소 0.2 MPa에서 최대 2.5 MPa일 것으로 예측되었다.

The rubber was compounded with carbon black and silica series-filler to examine the effects of the various rubber fillers on a gasket material’s suitability and fuel cell stack conclusion. The evaluation of a long term heat resistance and oil resistance of the mixed rubber material was performed considering at the drive environment of PEMFC. Test results of compression set for the most influencing property of gasket showed that it was about less than 15% at long term of up to 1000 h. In this experiment, FEM analysis is carried out about the rubber material’s properties depending on each filler and the stress which is produced when a gasket is contracted by using various filler. Sealing force was expected to maximum 2.5 MPa from minimum 0.2 MPa by using FEM (finite element method) at stacking gasket to gasket.
