Method of manufacturing electricity generating assembly

A method of manufacturing an electricity generating assembly having a membrane electrode assembly and a pair of gas diffusion layers that are disposed on first and second surfaces of the membrane electrode assembly, the method comprising:

• blending a coupling agent with precursor compounds of the gas diffusion layers to produce a composition in which the coupling agent is contained;
• producing the gas diffusion layers using the composition in which the coupling agent is contained;
• applying a coupling agent-friendly adhesive to surfaces of the gas diffusion layers to form adhesion layers on the surfaces of the gas diffusion layers;
• and
• stacking the gas diffusion layers on the surfaces of the membrane electrode assembly to cause the adhesion layers to come into contact with the first and second surfaces of the membrane electrode assembly.

A method of manufacturing an electricity generating assembly having a membrane electrode assembly and a pair of gas diffusion layers that are disposed on first and second surfaces of the membrane electrode assembly, the method comprising:

• immersing the gas diffusion layers in an organic solvent in which a coupling agent is dispersed, to modify surfaces of the gas diffusion layers;
• applying a coupling agent-friendly adhesive to the surfaces of the gas diffusion layers, to form adhesion layers on surfaces of the gas diffusion layers;
• and
• stacking the gas diffusion layers on the first and second surfaces of the membrane electrode assembly, to cause the adhesion layers to come into contact with the first and second surfaces of the membrane electrode assembly.
