METHOD OF MANUFACTURING PLANAR MEMBRANE ELECTRODE ASSEMBLY FOR FUEL CELL AND CORRESPONDING PLANAR MEMBRANE ELECTRODE ASSEMBLY FOR FUEL CELL

摘要

Disclosed are a method of manufacturing a membrane electrode assembly for a fuel cell and a membrane electrode assembly for a fuel cell manufactured using the same. The planar membrane electrode assembly for a fuel cell may include an ionomer membrane (131, 132, 141, 142) formed in the gaps between side surfaces of electrodes (120) and on the electrode surfaces and an electrolyte membrane, thereby increasing interfacial bonding force between the electrode and the electrolyte membrane (150, 160) and improving the durability of a cell. In addition, the membrane electrode assembly may include planar or smooth surfaces such that formation of voids or surface steps between the electrode (120) and a sub-gasket (170) may be prevented, thereby improving airtightness and preventing deterioration attributable to concentration of pressure.
