ABSTRACT:
A method for manufacturing a membrane electrode assembly comprises a process for preparing a electrolyte membrane and two gas diffusion layers, and a bonding process for forming the membrane electrode assembly by pressing a layered unit in which the electrolyte membrane is sandwiched between each of the two gas diffusion layers in such a way that provided catalyst layers locate in the interfaces between the electrolyte membrane and the two gas diffusion layers, wherein the bonding process is undertaken in a condition in which the surfaces of the electrolyte membrane are temporarily liquefied or softened.
