<P>PROBLEM TO BE SOLVED: To provide a method for generating electric power from a fuel regenerable fuel battery using a secondary alcohol as a fuel, and to provide a method for regenerating the fuel. <P>SOLUTION: It is discovered that a redox reaction of the second alcohol and a ketone is efficiently brought about when a special alloy electrode is used, and this electrode is used as a fuel pole of the fuel battery. In the fuel battery having the fuel pole, an air pole and an electrolyte film interposed between the fuel pole and the air pole, the fuel pole is made of an alloy of at least one type selected from the group consisting of ruthenium, tin, tungsten, copper, gold, manganese, vanadium and platinum. The fuel battery has the fuel containing in a liquid state the secondary alcohol as a main component. The method for generating electric power includes a first step of generating electric power from the fuel battery by directly supplying the fuel to the fuel pole in the battery, a second step of bringing an oxidative substance to a contact with the air pole of the battery after the power generation, and conducting a current with the fuel pole used as a positive pole and the air pole as a negative pole by using an external power source, and a third step of again power generating electric power from the fuel battery undergoing the operation of the second step. <P>COPYRIGHT: (C)2004,JPO |
