ABSTRACT:
An extruded seal material which is stable in phosphoric acid is composed of fibrillating polytetrafluoroethylene, a halogenated oil, and a filler. Preferably the oil is a fluorocarbon oil and the filler is either non-fibrillating polytetrafluoroethylene, silicon carbide or graphite, all of which are stable in phosphoric acid at temperatures up to at least 400.degree. F. This seal material is particularly suited for use in the environment of a phosphoric acid fuel cell.
