Abstract
A method for manufacturing a membrane electrode assembly for a fuel cell, in which uniform pressure is applied to the entire area of an electrode during a transferring process to ensure uniformity of products. The method includes an electrode forming step of forming an electrode layer by coating an electrode slurry on a support; a transferring step of aligning the electrode layer on both surfaces of an electrolyte membrane and applying heat and pressure to transfer the electrode layer; and removing the support, wherein in the transferring step, gas pressure is applied to a gas pressure platen of a stretchable material to transfer the electrode layer to the electrolyte membrane.
