Abstract
The power generation efficiency of a microbial power generator is increased by using an easy and inexpensive unit. Two plate-like cation-exchange membranes are disposed in parallel in a tank. This arrangement allows an anode chamber to be formed between the cation-exchange membranes. Two cathode chambers are separated from the anode chamber by using the respective ion-permeable nonconductive membranes. An oxygen-containing gas is made to pass through the cathode chamber. An anode solution is supplied to the anode chamber, and, preferably, the anode solution is made to circulate. A biologically treated exhaust gas is used as the oxygen-containing gas to be supplied to the cathode chamber. Carbon dioxide in the biologically treated exhaust gas can promote transport of Naand Kions, and water vapor can increase the ion permeability, thereby increasing the power generation efficiency.
