초록 ▼

A miniaturized microbial fuel cell is described deriving electrical power from the biological activity of microbes, typically the metabolism of glucose by baker's yeast. Microfabrication techniques are used to miniaturize the components as well as the overall fuel cell and are capable of integration with other biomedical and implantable devices. Substantial reductions in both the size and the cost of implantable systems are thereby achievable. Electrode structures are used that facilitate electron transfer and power production giving favorable power densities in a miniature fuel cell. In addition, the microbial fuel cell of the present invention extracts glucose or other metabolite(s) from the ambient body fluids as its fuel, thus achieving a renewable, long-term power source for implantable biomedical devices.

What is claimed is: 1. A microbial fuel cell comprising: a) an anode in an anode compartment and in contact with an anolyte containing a plurality of electricity-producing microbes and nutrient substances therefore, further comprising means for nutrient ingress and waste egress from said anode compartment; and, b) a cathode in a cathode compartment in contact with a catholyte containing materials therein capable of accepting electrons from said cathode, further comprising means for oxygen ingress and waste egress from said cathode compartment; and, c) a proton exchange membrane configured so as to allow passage of protons from said anode compartment to said cathode compartment; and, wherein said anode comprises a substrate having a plurality of substantially parallel microchannels therein, wherein said microchannels have a current collecting coating thereon, and said coated microchannels have dimensions so as to provide no substantial impediment to the flow of said microbes therethrough; and, wherein said microbes are bacteria. 2. A microbial fuel cell as in claim 1 further comprising an electron mediator in said anolyte. 3. A microbial fuel cell as in claim 1 wherein said microbe is baker's yeast. 4. A microbial fuel cell as in claim 1 wherein said nutrient is glucose. 5. A microbial fuel cell as in claim 1 wherein said electron mediator is methylene blue. 6. A microbial fuel cell as in claim 1 wherein said electron accepting material is iron ferricyanide ion.
