Abstract:
Provided is a microbial fuel cell which is capable of stably generating electricity and in which a pump or the like for fuel supply is not necessary and low oxygen concentration is maintained in the vicinity of a fuel electrode. A microbial fuel cell ( 1 A) includes: a housing ( 2 ) that defines a closed space isolated from an external environment; and an ion-conductive layer ( 5 ) that divides the closed space into a fuel chamber ( 3 ) and an air chamber ( 4 ), the fuel chamber ( 3 ) being configured to have therein a microorganism-containing substance ( 10 ), the air chamber ( 4 ) containing oxygen therein. The housing ( 2 ) has, in at least part thereof, a hole ( 6 ) through which the external environment and the fuel chamber ( 3 ) are in communication with each other. The housing ( 2 ) is provided with an openable/closeable member ( 7 ) configured to be able to open and close the hole ( 6 ).

Claim (Index 1):
A microbial fuel cell comprising:\n a housing that defines a closed space isolated from an external environment; an electrolyte layer with proton conductivity, the electrolyte layer dividing the closed space into a fuel chamber and an air chamber, the fuel chamber being configured to have therein a microorganism-containing substance, the microorganism-containing substance containing an exoelectrogen, an aerobic bacterium, and a fuel substance, the air chamber having oxygen therein; a negative electrode that is disposed in the fuel chamber and that is configured to receive an electron produced by decomposition, by the exoelectrogen, of organic matter in the fuel substance; and a positive electrode that is disposed in the air chamber so as to be in contact with the electrolyte layer and that is configured to donate an electron to oxygen, the housing having, in at least part thereof, a hole through which the external environment and the fuel chamber are in communication with each other, the housing being provided with an openable/closeable member configured to be able to open and close the hole.
