PURPOSE:To provide a small-sized battery with large current output by supplying an oxidating agent such as oxygen to one of the outer sides of an electrode film inside of or outside of a hollow type film, feeding a fuel such as hydrogen to the other so as to have power generation, and therein breaking the film even though the pressure balance of the fuel and oxidating agent has collapsed. CONSTITUTION:Neg. electrode reaction takes place on the neg. electrode 5 side with the aid of catalyst 4 to cause separation of hydrogen into a hydrogen ion and an electrode, and the hydrogen ions are given to the electrolyte 3. On the pos. electrode 2 side hydrogen ions produced from the electrolyte 3 makes pos. electrode reaction, and water is produced from oxygen, hydrogen ion, and electron. Electrons produced in this neg. electrode reaction flow to the load through a wiring, not illustrated, connected to the electrode 5, to then reach the electrode 2, and there is used to pos. electrode reaction. As the hollow type film 1 has very fine porosity, the strength remains large even though the distance between electrodes 2, 5 is lessened, and therefore, enlargement of the pressure difference between outside and inside of the hollow type film will not lead to breakage of the film. |
