This research presents a simple procedure for chemically modifying yeast (Saccharomyces cerevisiae) cells with nickel hexacyanoferrate (NiHCF) and ferric hexacyanoferrate, also known as Prussian blue (PB), to increase the conductivity of cell wall. Using linear sweep voltammetry, NiHCF-modified PB-modified (NiHCF/yeast PB/yeast, respectively) were found have better wall in [Fe(CN)6]3− glucose-containing phosphate-buffered solution than unmodified yeast. Spectrophotometric analysis showed that modification NiHCF had less harmful effect on viability PB. The use NiHCF/yeast PB/yeast construction yeast-based fuel allowed maximum power densities 62.66 mW/m2 94.09 be achieved. These values much higher those obtained using (42.25 mW/m2). renewed by replenishing suspension anolyte or FeCl3 salt catholyte. 77.4% 50.1% initial density
