NOVELTY - Membrane electrode assembly (I) comprises: (a) two electrochemically active electrodes (1, 3) separated by a polymer electrolyte membrane (A) (5); and (b) two gasket layers (15, 17) made of a first gasket material, where the first gasket layer (B) (15) partially covers the front of (A) and/or the first electrode and the second gasket layer (C) (17) partially covers the back of (A) and/or the second electrode (3).    USE - (I) is useful for producing fuel cells which has high long term stability.    ADVANTAGE - (I) simplifies the production of the fuel cell saving on time and costs.    DETAILED DESCRIPTION - Membrane electrode assembly (I) comprises:    (a) two electrochemically active electrodes (1, 3) separated by a polymer electrolyte membrane (A) (5), where the surfaces of (A) are in contact with the electrodes in such a way that the first electrode (1) partially or totally covers the front of (A) and the second electrode (3) partially or totally covers the back of (A); and    (b) two gasket layers (15, 17) made of a first gasket material, where the first gasket layer (15) partially covers the front of (A) and/or the first electrode and the second gasket layer (17) partially covers the back of (A) and/or the second electrode; and further comprises a second gasket material (7, 9) on the front of the first gasket layer and on the back of the second gasket layer; each of the gasket layers comprises at least one recess (11, 12); and the second gasket material (7) on the front of first gasket layer is in contact with the second gasket material (9) on the back of the second gasket layer.    INDEPENDENT CLAIMS are also included for:    (1) a method for the production of (I); and    (2) a fuel cell comprising at least one (I).
