NOVELTY - A catalyst coated membrane is manufactured by applying electrocatalyst coating composition (20) to element (10) having polymer membrane (12), drying composition to form first electrode (14), applying second stable temporary substrate to first electrode, removing first stable substrate from the membrane, applying composition to portion of second surface (12) of the membrane, and drying the composition on the membrane.    USE - The invention is used in electrochemical cells, preferably a fuel cell (claimed).    ADVANTAGE - The invention is suitable for high volume production of Catalyst Coated Membranes. It avoids swelling problems associated with known processes and does not require complicated pre-treatment or post-treatment processes.    DETAILED DESCRIPTION - The manufacture of catalyst coated membrane involves applying electrocatalyst coating composition to element comprising polymer membrane having first and second surfaces and first dimensionally stable temporary substrate, in which the composition is applied to portion of the first surface of the polymer membrane; drying the composition to form first electrode on the polymer membrane; applying second stable temporary substrate to the first electrode; removing the first substrate from the polymer membrane; applying the coating composition to portion of the second surface of the polymer membrane; and drying the composition on the polymer membrane to form a sandwich comprising the second electrode, the polymer membrane, the first electrode, and/or the second substrate.    An INDEPENDENT CLAIM is also included for a fuel cell prepared by the above process.    DESCRIPTION OF DRAWING(S) - The figure shows a process employing first and second substrates and coating stations to apply electrocatalyst compositions to the membrane to form electrode layers.
