Abstract
The present invention relates to a gasketed membrane-electrode assembly comprising gaskets arranged on each side of a membrane-electrode assembly including a cathode, an anode, and a polymer electrolyte membrane, in which the gaskets are multilayered films comprising an elastic layer and an adhesive layer formed on each side of a support layer. According to the present invention, the gasket film can be united with the polymer electrolyte membrane, and the leakage of fuel gas and oxidizing gas decreases on operation of a fuel cell. In addition, various materials can be selected for each layer of the gasket. Thus, it can be suitable for mass production of a polymer fuel cell due to its simple manufacturing process.
