Abstract
A fuel cell body has an anode having an anode-side separator with projections and depressions formed on its surface, a cathode, and a membrane electrode assembly disposed between the anode and the cathode, and the fuel cell body is disposed in a container for storing liquid fuel so that at least the anode side is immersed therein. Fuel passageways through which the liquid fuel flows are formed by regions surrounded by the projections and depressions on the surface of the separator and the membrane electrode assembly. By this, the downsized, simplified and lower power consuming structure of auxiliary equipment such as a fuel feed system is achieved.
