Direct Ethanol Fuel Cell (DEFC) Fabricated with Ceramic Membrane

Abstract

Direct ethanol fuel cell has been fabricated with ceramic membrane. A porous silicon carbide (SiC)membrane having approximately 30% porosity has been applied for a direct ethanol proton exchange membrane(DE-PEM) fuel cell. A horizontal type cell having Pt (18mg/cm2) catalyst layer on both side of the ceramic membranewas used for the demonstration test. The ethanol oxidation based-fuel cell stack showed very high voltage (1.289V)and measurable current level (68mA) even though at room temperature. PU - The Korean Hydrogen And New Energy Society
