1. A microbial fuel cell, comprising:
- a cathode comprising a membrane, the membrane forming a cathode wall generally enclosing and defining an interior space, the cathode wall having an internal surface adjacent the interior space and an opposed external surface, the wall extending between a first end and a second end;
an anode, the anode substantially non-toxic to anodophilic bacteria; and
an electrically conductive connector connecting the anode and the cathode.

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.
