NOVELTY - A membrane electrode gasket assembly (MEGA) component representing an essential part of polymer electrolyte fuel cells is produced by a forming process in which electrodes (3) are embedded in a gasket. The forming process starts from a large assembly that is subsequently split into standard size components.    USE - Polymer electrolyte fuel cell production.    ADVANTAGE - The invented process, which involves embedding the membrane electrode assembly (MEA) in the gasket to produce the MEGA, ensures good gas impermeability as the number of MEA assemblies increase, eliminates waste of membrane material caused by overlapping of membrane material with the electrode, reduces the number of processes involved in assembling the stack, and obviates the need to produce each MEA individually.    DETAILED DESCRIPTION - The membrane electrode gasket assembly (MEGA) component comprises two electrodes (3) heat-sealed onto a proton exchange membrane (4) and an insulating gasket (2). An assembled component whose membrane does not overlap the sides is embedded in a gasket (2) as a result of injected gasket-forming material working its way between the pores (3') of the electrodes so as to form a MEGA single component (6).    The structural configuration of the MEGA (6) allows a convenient manufacturing sequence that involves the production of a large assembly that is subsequently mechanically split into several smaller sized components (7). The smaller-sized components are then embedded in the gasket (2) by means of a known material injection process and remain inseparably bonded with the gasket (2), which forms the peripheral seal of each individual assembly. Each assembly thus fashioned is placed between two collectors (1) to form one of the cells that make up the stack.
