NOVELTY - The fuel cell has anode chamber, cathode chamber, proton membrane component, silica gel gasket, fastening bolt and pedestal. The anode and cathode chambers are seal head type cylinder structures. The circumferences of the walls of the chambers and the corresponding circumferences of silica gel gaskets are provided with bolt holes whose diameters and the number are the same. The bolts holes are fixed through the fastening bolts after assembled. The pedestal is fixed with the bottom surface of the columnar fuel cell.    USE - Columnar microbiological fuel cell.    ADVANTAGE - By using column shaped housing for fuel cell, the distance between the anode chamber and cathode chamber is decreased, so that the resistance of the cell is reduced and the power is improved. The silica gel spacers are arranged between the proton membrane and separation board, so that the sealing performance is improved, and the oxygen of the cathode cannot be diffused to the anode, thus the Columbic efficiency of the cell is enhanced. The structure of fuel cell is simplified and the cost is reduced.    DETAILED DESCRIPTION - The upper portions of chambers are respectively provided with electrode insertion holes, sampling holes with sealing plug and venting holes. The silica gel gaskets are respectively located among the chambers and proton membrane component. The anode carbon paper and cathode carbon paper are respectively arranged in anode and cathode chambers and are extended from electrode insertion holes through conductors. The surface of cathode carbon paper is plated with platinum catalyst and the bottom portions of the chambers are provided with gas inlet holes. The gas inlet holes are divided into the liquid inlet holes and liquid outlet holes. The proton membrane component is provided with square shaped proton membrane, two base plates and two silica gel spacers. The proton membrane is clamped between spacers and fixed through base plates. The center portions of spacers and base plate are provided with square holes. The side length of square hole is shorter than the side length of proton membrane. The base plates and pedestal are made of polymethyl methacrylate.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the fuel cell.
