PROBLEM TO BE SOLVED : To provide a liquid fuel direct type fuel cell, and an apparatus using the same for achieving : (A) No supplimentary mobile power is required for fuel supply, (B) Driving is allowed in any attitude, (C) An operation is simple for supplying fuel, (D) The cross leakage and cross over of liquid fuel are rare, (E) Both a power density and an energy density are high, and (F) Safety and reliability are high, in the case when the fuel cell is mounted on a portable information device or a portable instrument, or used as a portable secondary power source. SOLUTION : The fuel cell incudes an anode for oxidizing the liquid fuel, a cathode for reducing oxygen, and a liquid fuel tank. The liquid fuel is supplied to the anode by capillary phenomenon, and the amount of the supply is regulated by the gas exchange with an anode exhaust gas. COPYRIGHT : (C)2008, JPO&INPIT
