ABSTRACT:
A DMFC is provided in which the structure is simplified and the thickness is reduced without impairing diffusibility of fuel, air and generated products. An anode catalyst layer and a cathode catalyst layer sandwich an electrolyte membrane. Liquid fuel stored in a fuel chamber is directly supplied to the anode catalyst layer. Current collectors are respectively provided adjacent to the anode catalyst layer and the cathode catalyst layer. Each of the current collectors is formed of a flat conductive sheet in which a plurality of fine pores are provided to extend through the current collector in a direction substantially perpendicular to the planar direction.
