Abstract

Cellulose is one of the most abundant renewable resources in the world. Cellulose has previously been investigated to produce H₂, ethanol and biogas mainly through biological fermentation processes. It was recently shown that cellulose could also be used to directly generate electricity in a two-chamber Microbial fuel cell (MFC) or to generate hydrogen in a two-chamber microbial electrolysis cell (MEC). However, the power density or H₂ rate was low. We report here that a maximum power density of 1080 mW/m² can be obtained using cellulose in a single-chamber MFC with a Pt-catalyzed air-cathode and carbon fiber brush anode. This power density is around 20 times higher than that previously obtained using a two-chamber bottle MFC. By using single-chamber MEC, we achieved hydrogen recoveries of up to 75 % and a hydrogen production rate of 0.5 m³-H₂ per m³ reactor volume per day at an applied voltage of 0.8 V.
