Abstract

Biofilms of natural anaerobic microbial consortia externally grown on Gas Diffusion Electrodes (GDL) in a bioreactor, were investigated within a Membrane-Electrode-Assembly with respect to lifetime and electricity production upon variation of biodegradable materials with an oxygen demand of 1000mg/l as simulated waste water.
A remarkable differentiation and plasticity of the films is observed, to resist the toxicity of 0.5 mg/cm² Pt used on the inner side of the anode for smooth hydrogen combustion and to recover bioactivity upon alteration of the biodegradable material. Such robust biofilms are intended to provide a new technology for water purification and electricity production from industrial and community wastewater.
