摘要：
A manufacturing method of Membrane-Electrode-Gasket Assemblies (MEGAs) used for polymer electrolyte fuel cells (PEFCs) is described wherein a polymer electrolyte membrane is formed directly on a electrode. A typical PEFC is constructed by assembling membrane-electrode assembly (MEA), gaskets, and separators. According to the invented method, PEFC is fabricated by assembling separators and MEGA, into which MEA and a gasket are integrated. Compared to the conventional MEA-gasket assemblies, MEGAs are easy to handle and can be mass-produced via a manufacturing process in a series. Moreover, employing MEGAs improves PEFC performance since the membrane thickness of MEGAs is lower than that of the conventional MEA-gasket assemblies.
