Abstract
A fuel cell which can utilize the fuel in its fuel reservoir to the fullest possible extent. The fuel cell includes: an electrolyte layer; a first electrode which is provided on one surface of the electrolyte layer and to which a liquid fuel is supplied; and a second electrode which is provided on the other surface of the electrolyte layer and to which an oxidant is supplied. The fuel cell further includes: a fuel chamber which is provided next to the first electrode and stores the liquid fuel; a fuel reservoir which is provided next to the fuel chamber and stores the liquid fuel to be refilled into the fuel chamber; a selectively permeable unit which is provided between the fuel chamber and the fuel reservoir and is permeable to the liquid fuel; and an osmotic pressure generating source which dissolves in a liquid stored in the fuel chamber and does not permeate the selectively permeable unit.
