Abstract:
A membrane electrode assembly comprising two electrode separated by a polymer electrolyte membrane wherein the surfaces of the membrane are in contact with the electrodes so that the first electrode partially or totally covers the front of the membrane and the second electrode partially or totally covers the back of the membrane; two gasket layers wherein the first gasket layer partially covers the front of the membrane and/or the first electrode and the second gasket layer partially covers the back of the membrane and/or the second electrode the assembly also comprises a second gasket material 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; the second gasket material on the front of the first gasket layer is in contact with the second gasket material on the back of the second gasket layer.
