ABSTRACT:
A direct methanol type fuel cell comprises at least one fuel cell unit including an anode and a cathode and a plurality of separators. Each of the separators comprises an aqueous methanol solution flow-adjusting plate having grooves formed in parallel to a direction of gravity, and an oxygen containing gas flow-adjusting plate having grooves formed. A methanol tank and a water tank are connected to a supply passage through pumps respectively. The supply passage communicates through a passage to the aqueous methanol solution flow-adjusting plate. The aqueous methanol solution flow-adjusting plate 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.
