NOVELTY - A fuel cell comprises fuel storage unit (210) storing a liquid fuel; a pressure application unit (400) applying pressure to liquid fuel stored in the fuel storage unit; and liquid fuel vaporization unit of a nonporous type vaporizing the liquid fuel pressed by the pressure application unit to supply the vaporized fuel to the negative electrode as the gaseous fuel.    USE - The fuel cell is used for vaporizing a liquid fuel stored in a fuel storage unit and uses the vaporized fuel gas to generate electric power. The fuel cell is used as battery functioning as a driving power source and a memory retention power source for portable type electronic equipment e.g. cellular phones, personal digital assistants and notebook type personal computers.    ADVANTAGE - Back pressure is applied to a liquid fuel stored in a fuel storage unit by a pressure application unit, and a liquid fuel vaporization membrane (220) that vaporizes the liquid fuel to thus supply the vaporized fuel gas to an anode (10) is formed by a nonporous membrane. Backed by this, the liquid fuel can be prevented from leaking out to the anode, so that the concentration of the liquid fuel can be increased to an optimum level. As a result, the power generation efficiency can be improved.    DETAILED DESCRIPTION - A fuel cell comprises:    (1) a power generation unit (100) configured to include a positive electrode that reduces oxygen as an active material, a negative electrode that oxidizes a gaseous fuel, and an electrolyte layer provided between the positive electrode and the negative electrode;    (2) a fuel storage unit storing a liquid fuel;    (3) a pressure application unit applying pressure to the liquid fuel stored in the fuel storage unit; and    (4) a liquid fuel vaporization unit of a nonporous type vaporizing the liquid fuel pressed by the pressure application unit to supply the vaporized fuel to the negative electrode as the gaseous fuel.
