    摘要: The invention mainly concerns a fuel cell seal (52) designed to be affixed on a bipolar plate (22) in the form of a membrane whereof the profile corresponds approximately to the peripheral frame (50) of the bipolar plate (22) and comprising a central opening (66) coinciding approximately with the central zone (46) dispensing the reagents of the bipolar plate (22). The invention also concerns a fuel cell comprising an electrode membrane assembly (70) which includes in particular an active region (74), which is the site of anode and cathode reactions, and a peripheral frame (75) and which is sandwiched between two bipolar plates (22) whereon is affixed the inventive seal (52).
