Abstract: PURPOSE: A method for stabilizing structure of a membrane electrode assembly is provided to improve interface stability between an electrolyte membrane and a catalyst layer, by modifying edge parts of a polymer electrolyte membrane, which are not coated with a catalyst. CONSTITUTION: In a method for stabilizing structure of a membrane electrode assembly, the fuel cell membrane electrode assembly comprises a polymer electrolyte membrane, and a catalyst layer coated on the polymer electrolyte membrane. The method comprises a step of heat-treatment of the part of the polymer electrolyte membrane which includes one or more of an edge region of a polymer electrolyte membrane, a gas inlet region, and an outlet region(20). By the heat-treatment, the interface of the electrolyte membrane and catalyst layer is stabilized.

Abstract: PURPOSE: A catalyst ink for an electrochemical device is provided to prevent primary pores in a catalyst layer from being clogged by a binder, thereby increasing the primary pores. CONSTITUTION: A catalyst ink for an electrochemical device includes a catalyst, an ionomer binder, and a solvent. The catalyst ink includes ortho-dichlorobenzene as a pore-forming agent. The pore-forming agent has a higher boiling point than that of the solvent and is non-soluble to the ionomer binder. The content of the 1,2-dichlorobenzene is 0.33-33.33 times of the weight of the catalyst. The weight ratio of the ionomer binder to the catalyst is 20-40 %. The catalyst is metal or alloy. The electrode for the electric chemical device is the coating layer of the catalyst ink.
