A direct methanol type fuel cell comprises at least one fuel cell unit (18, 118) including an anode (16, 116) and a cathode (14, 114) and a plurality of separators (20, 120). Each of the separators (20, 120) comprises an aqueous methanol solution flow-adjusting plate (82, 150) having grooves (82a, 150a) formed in parallel to a direction of gravity, and an oxygen containing gas flow-adjusting plate (80, 156) having grooves (80a, 156a) formed. A methanol tank (85) and a water tank (86) are connected to a supply passage (89) through pumps (87, 88) respectively. The supply passage communicates through a passage to the aqueous methanol solution flow-adjusting plate (82, 150). The aqueous methanol solution flow-adjusting plate (82, 150) is formed of a porous conductive material. Therefore, the aqueous methanol solution can be stably supplied at a uniform concentration to the entire operating surface of the anode (16, 116). <IMAGE> |
