Performance of dirrct methanol fuel cell using high porous active carbon as an uncataiysed diffusion layer in anode(com-posite electrode)has been evaluated. Effects of porous active carbon in anode were investigated by galvanostatic method and Fourier Transform Infrared
spectroscopy. The single cell was oprated with 2.5M methanol at temperature of 80-120\'C and showed performance of 210-510 mA/cm at 0.4V. BY relacing conventional electrode with compisite electrode, the increment of 90 mA/cm in current density was obtained at 90\'C and 0.4V.
