Abstract

Elastomer material gasket as an important component works in proton exchange membrane (PEM) fuel cell under moist, acidic conditions. The evolution process of the material's chemical degradation plays a fundamental role in studying the performance of mechanical seal gasket material and its life prediction. The chemical process of the elastomer material was analyzed by using X-ray photoelectron spectroscopy (XPS). The degradation mechanism was mainly molecular chain scission in the backbone and side chain and hydrolysis of crosslinking.
