Abstract:

Many bacteria can convert chemical energy to electrical energy they oxidize diverse organic substrates, transfer electrons to anodic electrodes and thus generate electricity in microbial fuel cells MFCs. In the marine environment, microbial fuel cells, termed either sediment or benthic microbial fuel cells, have been developed to generate power via anodic bacteria in the ocean sediment. Power is dependent upon enriched anodic bacteria that transport their electrons onto the anode. The marine deployed MFC systems can provide renewable, harvested power to trickle charge batteries or other storage devices. Through power management systems these storage devices can power traditional electronic loads of interest. The systems have the promise to allow for long term deployment of in-water sensor and communications systems, providing decreased maintenance and increased operational capabilities.
