PROBLEM TO BE SOLVED: To provide a flexible fuel cell in which the solution filled therein can be easily agitated and of which cell performance can be recovered.SOLUTION: An anode electrode sheet 1 and a cathode electrode sheet 2, which have oxidoreductase on their surfaces and to which current collectors 3, 4 are conductively connected via a conductive adhesive, are disposed opposite to each other, and a separator 5 comprising a proton penetration film is disposed between the two electrode sheets. In addition, a fuel accumulation part to be filled with fuel solution is provided at a position coming into contact with at least the anode electrode sheet to construct a cell part 9. Then, the cell part 9 is encapsulated by flexible encapsulation sheets 6, 7 to construct a flexible fuel cell 10.
Abstract:
PROBLEM TO BE SOLVED: To provide a bio-fuel cell in which a fuel solution for drinking is not contaminated and is easy to be recovered.SOLUTION: In a bio-fuel cell 1 of the present invention, an absorber 30 is attached to a cell 10. A fuel solution 50 of the cell 10 is absorbed and held by the absorber 30. The fuel solution 50 after use for power generation does not backflow from a fuel supply section 13, and the fuel solution is not contaminated. Thus the fuel solution 50 used such as commercial beverages can be used for both of drinking and power generation. Also, the fuel solution 50 can be recovered or eliminated only by removing the absorber 30 from the cell 10.
