A fuel cell capable of being thinned while maintaining a stable electric power supply is provided. A fuel cell includes a power generation section, a fuel tank, a fuel supply section (pump), and a fuel vaporization section. The power generation section has a structure in which a combined body is sandwiched between a cell plate and a cell plate. The combined body has a structure in which an anode electrode and a cathode electrode are oppositely arranged with an electrolyte film in between. In particular, the fuel supply section and the fuel vaporization section are integrally provided, and are connected by a nozzle section buried therein. A fuel contained in the fuel tank is pumped by the fuel supply section according to the state of the power generation section, and then is vaporized by the fuel vaporization section, and is supplied to the power generation section side.
