NOVELTY - A fuel cell includes a flow passage plate (6) defining separate first and second flow passages (13, 15) for feeding liquid fuel to fuel electrode (1) and for discharging gas from fuel electrode, respectively. The fuel electrode has a catalyst-containing electrode layer (16) on a side where electrolyte membrane (2) is provided and a diffusion layer (17) on a side where flow passage plate is provided. A supply suppression structure suppresses supply of liquid fuel from first flow passage to diffusion layer. A discharge acceleration structure accelerates discharge of gas from second flow passage.    USE - For e.g. portable telephones.    ADVANTAGE - Enough reaction at fuel electrode can be fulfilled even if liquid fuel is supplied to the first flow passage at low pressure, thus realizing a small-size, high-power fuel cell. The fuel cell can obtain stable output power regardless of the installation or holding direction of the fuel cell.    DETAILED DESCRIPTION - A fuel cell includes a fuel electrode to which liquid fuel is supplied and by which cations and electrons are generated from liquid fuel, an electrolyte membrane placed opposed to the fuel electrode and through which cations from fuel electrode permeate, and an oxidizer electrode (3) placed opposed to the electrolyte membrane and to which oxidizer is fed and by which cations that have permeated through the electrolyte membrane and oxidizer are made to react with each other. A flow passage plate is placed opposed to the fuel electrode and defines a first flow passage for feeding liquid fuel to the fuel electrode and a second flow passage for discharging discharge gas derived from the fuel electrode. The first and second flow passages are separated from each other. The fuel electrode has a catalyst-containing electrode layer on one side on which the electrolyte membrane is provided and a diffusion layer on another side on which the flow passage plate is provided. A supply suppression structure suppresses supply of liquid fuel from the first flow passage to the diffusion layer. A discharge acceleration structure accelerates discharge of discharge gas from the second flow passage. An area of an opening at which the first flow passage opens toward the diffusion layer side of fuel electrode is smaller than an area of an opening at which the second flow passage opens toward the diffusion layer side of fuel electrode.
