Abstract
A membrane electrode unit has a seal arranged on the edge region, wherein the seal in part penetrates into the edge region of the membrane electrode unit and in part fully covers the edge region outside the membrane electrode unit, which enables sealing of the gas chambers of a fuel cell and at the same time reliably interrupts a leakage path at the edge in membrane electrode units with flush cut. The membrane electrode unit is surrounded by a sealing frame which at least partially surrounds the edge region with the seal.
