Advanced apparatus for generating electrical power from aquatic sediment/water interfaces

Patent image
NRL

An improved benthic microbial fuel cell for generating energy at the interface of aquatic sediment and seawater includes an anode electrode embedded within the aquatic sediment, a cathode electrode positioned within the seawater and above the aquatic sediment, a rig for maintaining the relative positions of the anode and cathode electrodes, electrical leads extending from the anode and cathode electrodes to a load, wherein the anode electrode comprises a bottlebrush electrode residing within a permeable tube. The apparatus is easier to deploy than previously-described fuel cells, while being lighter, more durable, and generating greater power density. Also disclosed are methods of generating power from such an apparatus.
