Abstract

Devices for production of electricity and/or hydrogen gas are provided by the present invention. In particular, microbial fuel cells for production of electricity and modified microbial fuel cells for production of hydrogen are detailed. A tube cathode is provided which includes a membrane forming a general tube shape. An anode is provided which has a specific surface area greater than 100 m2/m3. In addition, the anode is substantially non-toxic to anodophilic bacteria. Combinations of particular anodes and cathodes are included in microbial fuel cells and modified microbial fuel cells.
