520	3		_aA single-chamber microbial electrolysis cell (MEC)that used a high density of nonmetal-catalyst carbon fibers as the anode achieved high volumetric current densities from 1470 ( 60 to 1630 ( 50 A/m3 for a hydraulic retention time of 1.6-6.5 h. The high current density was driven by a large anode surface area and corresponded to a volumetric chemical oxygen demand (COD)-removal rate of 27-49 kg COD/m3 ¡¤ d. Observed H2 harvesting rates were from 2.6 ( 0.10 to 4.3 ( 0.46 m3 H2/ m3 ¡¤ d, but the H2 production rates computed from the current densities were 16.3-18.2 m3 H2/m3 ¡¤ d. Tracking all significant electron sinks (residual acetate, H2, CH4, biomass, and soluble microbial products (SMP)) in the single-chamber MEC showed that H2 reoxidation by anode-respiring bacteria recycled H2 between the cathode and the anode, and this caused the large discrepancy in H2 production and harvest rates. H2 recycle accounted for 62-76
