PROBLEM TO BE SOLVED: To provide a fuel cell that appropriately removes impurities in a fuel electrode even if using a fuel supply source for generating a fuel by reacting a plurality of fuel precursors.SOLUTION: The fuel cell includes: a power generation section 2 having a fuel electrode 23, an oxidant electrode 22 and a solid polymer electrolyte membrane 21; a fuel electrode section having a fuel supply space 25 supplied with a fuel; and a fuel supply source 3 for bringing a plurality of fuel precursors 32 into contact with each other and causing a chemical reaction to generate the fuel and supplying the fuel. The fuel supply source has a plurality of storage sections for storing the plurality of fuel precursors, respectively, and a fuel control mechanism 33 for moving at least the fuel precursor stored in either storage section to the other storage section. The fuel control mechanism performs supply control of controlling the fuel precursor movement according to a physical quantity related to impurities accumulated in the fuel electrode by the reaction of the fuel with an oxidant, so that the pressure of the fuel caused by the supply control removes at least part of the impurities.
