MEMBRANE ELECTRODE ASSEMBLY(MEA) USING NANO CARBON MATERIALS FOR FUEL CELL AND METHOD FOR THE SAME

摘要

PURPOSE: A membrane electrode assembly using carbon nano material is provided to alleviate material transfer resistance and have excellent durability by including a catalyst layer with carbon nano supporter comprising a carbon black. CONSTITUTION: A membrane electrode assembly using carbon nano material comprises an electrolyte membrane and electrode. The electrode comprises a catalyst layer. The catalyst layer is in the both sides of the electrolyte membrane. The catalyst layer comprises conducting material of 0.05- 0.3 parts by weight relative to a carbon nano supporter of 1 part by weight. The catalyst layer mainly consists of a metal deposition electrocatalyst including a high endurance carbon nano supporter of a two dimensional structure and additionally consists of conductive material of a three dimensional structure and an ionomer binder for forming pores. The carbon nano supporter is the one or more kind of mixture which is selected from the group of a carbon nano fiber, carbon nano tube, carbon nano wire, carbon nano ring, and carbon nano horn.
