Abstract
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 formed on both side surfaces of an electrode and between the electrode and an electrolyte membrane, thereby increasing interfacial bonding force between the electrode and the electrolyte membrane 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 and a sub-gasket may be prevented, thereby improving airtightness and preventing deterioration attributable to concentration of pressure.
