Abstract
Pt/Nafion self-humidifying membranes for Polymer Electrolyte Membrane Fuel Cell (PEMFC) were synthesized via a supercritical-impregnation method. The Nafion 112 membranes were impregnated with Pt(II) acetylacetonate from a supercritical carbon dioxide (
초임계함침법을 이용하여 백금을 나피온 112 막에 함침시켜 자가 가습 막을 제조하였다. 초임계이산화탄소를 용매로 하여 나피온112 막에
