Abstract:
1. A fuel cell comprising: a fuel electrode to which a liquid fuel is supplied and by which cations and electrons are generated from the liquid fuel; an electrolyte membrane which is placed so as to be opposed to the fuel electrode and through which cations from the fuel electrode permeate; an oxidizer electrode to which an oxidizer is fed and which is placed so as to be opposed to the electrolyte membrane and moreover by which the cations that have permeated through the electrolyte membrane and the oxidizer are made to react with each other; and a flow passage plate which is placed so as to be opposed to the fuel electrode and which defines a first flow passage for feeding the liquid fuel to the fuel electrode and a second flow passage for discharging discharge gas derived from the fuel electrode, wherein the first flow passage and the second flow passage are separated from each other, and wherein 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, the fuel cell further comprising: a supply suppression structure for suppressing supply of the liquid fuel from the first flow passage to the diffusion layer, and a discharge acceleration structure for accelerating discharge of the discharge gas from the second flow passage.
