PROBLEM TO BE SOLVED: To provide a microbiological power generation device with an improved generation efficiency. SOLUTION: In the microbiological power generation device, a first conductive filling material 21 holding microorganism is composed of a porous body(for example, a graphite sheet of about 3-20 mm thick) having permeable blocks. The first conductive filling material 21 exists thoroughout an anode chamber 11 so that it makes an almost same shape with an inner shape of the anode chamber 11. As a result, a short pass of undiluted solution which contains electron donor and is supplied to the anode chamber 11 is prevented and the solution is supplied to the microorganism through the first porous conductive filling material 21. Then, a nonconductive membrane 15 separating the anode chamber 11 from a cathode chamber 12 and a second conductive filling material 22 arranged in the cathode chamber 12 are bonded tight with each other by using preferably a member such as a spacer 18 or the like. Preferably, the first conductive filling material 21 is bonded tight with the nonconductive membrane 15. COPYRIGHT: (C)2009,JPO&INPIT |
