An object of the present invention is to provide an anode for a microbial fuel cell, a microbial fuel cell, and a method for producing a microbial fuel cell anode capable of improving electron production and electron transfer efficiency and maintaining high power generation efficiency for a long period of time. An anode 40 for a microbial fuel cell according to the present invention is characterized in that a polymer-containing gel 44 containing electro-generated microorganisms 46 that decomposes organic matter 12 to produce electrons is immobilized on an electrode substrate of the anode 40. It is said. The immobilization material used for the polymer hydrogel 44 has a molecular weight of 1000 to 12000, preferably 1000 to 6000. The immobilization material used for the polymer hydrogel 44 has an addition concentration of 5% to 20%, preferably 8% to 15%. [Selection] Figure 1 |
