More particularly, it relates to a direct methanol fuel cell in which the material for controlling the diffusion rate of fuel is interposed between an anode and a fuel reservoir or positioned within the fuel reservoir, and thus, the diffusion rate of methanol is reduced even when using high concentration methanol fuel, such that the injected methanol is completely reacted in a catalyst layer so as to fundamentally reduce unreacted methanol, thereby suppressing the methanol crossover phenomenon and exhibiting high power density. In the inventive direct methanol fuel cell, the diffusion rate of fuel is controlled using the fuel diffusion rate-controlling material so as to suppress the methanol crossover phenomenon, thereby increasing energy density and output density.
