Abstract
A membrane electrode assembly and a method of manufacturing an electricity generating assembly include a pair of gas diffusion layers disposed on both surfaces of the membrane electrode assembly. Coupling agents are applied on surfaces of the gas diffusion layers, modifying surfaces of the gas diffusion layers. A coupling agent-friendly adhesive is applied to the surfaces of the gas diffusion layers to which the coupling agents are applied, forming adhesion layers on surfaces of the gas diffusion layers. The gas diffusion layers are stacked on the surfaces of the membrane electrode assembly, causing the adhesion layers to come into contact with the first and second surfaces of the membrane electrode assembly.
