MEMBRANE ELECTRODE ASSEMBLY, ELECTROCHEMICAL SENSOR OF USING THE SAME AND METHOD OF FABRICATING THEREOFS

摘要

PURPOSE: A membrane electrode assembly, electric chemical sensor using the same, and a method manufacturing the same are provided to utilize a carbon nano tube in which metallic nano particles are attached as a catalyst electrode layer and membrane electrode assembly as an electric chemical sensor of good quality. CONSTITUTION: A membrane electrode assembly comprises a polymer electrolyte membrane(200) and a catalyst electrode layer. The polymer electrolyte membrane has hydrophobicity. The catalyst electrode layers are formed on the both surfaces of the polymer electrolyte membrane. The catalyst electrode layer comprises a carbon nano tube and metallic nano particles and has metallic nano particle-carbon nano tube structure.
