The high conductivity and active surface area, combined with biocompatibility for working bacteria, is one of the biggest challenges for microbial fuel cells (MFCs). Prospective investigation of electrodes with a foam structure of carbonized polymers with ferrocene catalysts in a regular MFC with Escherichia coli, glucose and methylene blue as a mediator is presented. The electrode structures have been characterized by XRD and TEM, and showed a large number of nanotubes with large defects, in a randomly interconnected network. The characteristics of the MFC related to carbon structures and biocompatibility are described.
