PROBLEM TO BE SOLVED: To provide a compact electric power source disusing a separator nor a supplemental device like fluid supplying system, and to provide a portable electronic equipment using the same. SOLUTION: For the fuel cell, fuel cell electricity generating device, and the equipment using the same, the fuel cell comprises an anode oxidizing liquid fuel, a cathode reducing oxygen, and an electrolyte film insulating the anode and the cathode. The fuel cell has a hollow supporting structure, and an electricity generating part is formed by arranging the anode 3, the electrolyte film 2, and the cathode 4 on the outer peripheral surface of the hollow supporting structure 1, and the fuel contacts at the inside of the hollow supporting structure, and the air including oxygen contacts at the outside of the electricity generating part. |
