INTERFACE SEAL FOR A FUEL CARTRIDGE

摘要

A resilient sealing member (27) has a first face (40) and a second face (41) and an aperture (42) extending between the first face and the second face. At least two, preferably three or more, circumferential ridges (43, 44, 45) surround the aperture on the first face. Channels (46, 47) may be disposed between each adjacent pair of circumferential ridges and a flat seal may be provided on the first face, peripheral to the circumferential ridges. The flat seal may occupy a different plane than the plane occupied by apexes of the circumferential ridges. The resilient sealing member may be incorporated into interface seal assembly comprising a rigid frame (26) onto which it is moulded. The rigid frame may comprise a printed circuit board (25). The interface seal assembly allows for an easily interchangeable seal on a refillable fuel cartridge (1) for a fuel cell apparatus.
