Patent ID: 7479342

Claim:
A fuel cell comprising: a fuel cell body including an anode having an anode-side separator that is flat in a thickness direction and has projections and depressions formed on a surface of the anode-side separator, a cathode disposed so as to face the anode, and a membrane electrode assembly disposed between the anode and the cathode; and a container for containing liquid fuel which is to be fed to the anode, the container housing at least the anode of the fuel cell body so as to be immersed in the liquid fuel, wherein the fuel cell body has passageways surrounded by the projections and depressions formed on the surface of the anode-side separator and a surface of the membrane electrode assembly, the fuel passageways are connected to a feed port and a discharge port so as to extend in substantially one direction from the feed port to the discharge port, the discharge port being provided at a position higher than that of the feed port, and wherein the fuel passageways are disposed so as to be inclined relative to a direction extending from the feed port to the discharge port.
