Abstract
Official abstract text for this publication.
By a microbial fuel cell including: an anode electrode that includes, as a catalyst, current-generating bacteria supplied from soil or mud, and oxidizes an organic fuel supplied from soil or mud; and a cathode electrode that reduces oxygen supplied from air or water, the microbial fuel cell having an oxygen permeation restricting layer between the anode electrode and the cathode electrode facing each other, it is possible to provide, at low cost, a microbial fuel cell having high power generation performance due to direct power generation from soil or mud and capable of being thinned and miniaturized.
First claim
Opening claim text (preview).
1 . A microbial fuel cell comprising: an anode electrode that includes, as a catalyst, current-generating bacteria supplied from soil or mud, and oxidizes an organic fuel supplied from soil or mud; and a cathode electrode that reduces oxygen supplied from air or water, the microbial fuel cell having an oxygen permeation restricting layer between the anode electrode and the cathode electrode facing each other. 2 . The microbial fuel cell according to claim 1 , wherein said oxygen permeation restricting layer is a layer formed of a hydrogel. 3 . The microbial fuel cell according to claim 2 , wherein said hydrogel is formed of a polymer sugar chain. 4 . The microbial fuel cell according to claim 1 , wherein a moisturizing layer is provided on said cathode electrode. 5 . The microbial fuel cell according to claim 1 , further comprising, on an anode electrode side of said oxygen permeation restricting layer, a casing having at least one hole through which at least either of a microorganism and a nutrient therefor is replaceable.
