DIRECT METHANOL FUEL CELL HAVING MICRO-PERFORATED CARBON PAPERS AS DIFFUSION LAYERS

摘要

PURPOSE: A direct methanol fuel cell including a carbon paper diffusion layer having micropores is provided to maximize the output and efficiency of a battery by rapidly discharging by-products and smoothing the supply of fuel and oxidizing agents by forming micropores on a carbon paper constituting a diffusion layer. CONSTITUTION: A direct methanol fuel cell including a carbon paper diffusion layer having micropores comprises: an electrolyte film in which a catalyst layer and a diffusion layer are successively arranged on one side of the electrolyte film; a fuel electrode to which a methanol solution is supplied as fuel; and an air electrode supplied with oxidation gas in which a catalyst layer and a diffusion layer are successively arranged on the other side of the electrolyte film.
