ANODE OF DIRECT METHANOL FUEL CELL AND DIRECT METHANOL FUEL CELL EMPLOYING THE SAME

摘要

The present invention provides an anode used in a direct methanol fuel cell and a direct methanol fuel cell employing that anode. They can prevent crossovers of methanol and water and also can control permeation of water, so as to achieve high power output. The anode comprises an anode catalyst layer 20 and a gas-diffusion layer 150, and the gas-diffusion layer comprises a porous sheet support mainly made of carbon. In the porous sheet support, a high packing density area 50 is formed near the surface.
