Abstract:
A direct methanol fuel cell includes a cathode catalyst layer; an electrolyte membrane; an anode catalyst layer; a first fuel control layer that is water-repellent and conductive and that has pores; a second fuel control layer that is water-repellent and conductive and that has larger pores than the those of the first fuel control layer; a third fuel control layer that is water-repellent and conductive and that has smaller porous than those of the first fuel control layer and those of the second fuel control layer; and an anode GDL layer that is water-repellent and conductive, wherein the membrane and the layers above are arranged in the above order.
