MICROORGANISM POWER GENERATION METHOD AND MICROORGANISM POWER GENERATION DEVICE

摘要

PPROBLEM TO BE SOLVED: To stably maintain high-efficiency power generation for a long period of time, by preventing degradation of power generation efficiency with time in a microorganism power generation device using an air cathode. PSOLUTION: As two sheets of plate-like cation exchange membranes 31, 31 are arrayed in parallel inside a tub 30, an anode chamber 32 is formed between the cation exchange membranes 31, 31, and two cathode chambers 33, 33 are formed separated from the anode chamber 32 with each cation exchange membrane 31. Oxygen-containing gas is circulated in the cathode chamber 33, anode solution L is supplied to the anode chamber, and, preferably, the anode solution is circulated. In the cathode chamber 33, cleaning solution containing acid is intermittently guided in or cleaning solution containing alkali is guided in after the cleaning solution containing acid is guided in to clean and remove scales, slime generated at and attached to an air cathode or the like as a cause of degradation with time of the power generation efficiency.
