Electricity production from synthesis gas in a multi‐electrode microbial fuel cell
Bibliographic record
Abstract
Abstract BACKGROUND Electricity production in single‐anode/cathode MFCs fed with simulated synthesis gas (syngas) as the sole electron donor has recently been demonstrated. This study evaluated the ability of a multi‐anode/cathode MFC fed with syngas to achieve improved volumetric efficiency at several operating temperatures and electrode arrangements . RESULTS A maximum power density of 33 mW (normalized to the anodic compartment volume) and a coulombic efficiency ( CE ) of 43% was achieved at an operating temperature of 37°C. MFC operation at 50°C resulted in a much lower power density of 10 mW and a CE of 15%. The MFC power density was greatly impacted by the electrode arrangement and the highest power density was achieved in a three anode–two cathode ( 3A‐2C ) arrangement . CONCLUSION The multi‐electrode design enhanced the performance of a syngas‐fed MFC , which could have major economic and operational implications for designing large‐scale syngas‐fed MFCs . The MFC performance at elevated temperatures was restricted by low microbial activity, implying that a thermophilic rather than a mesophilic inoculum might be required for successful operation under thermophilic conditions. © 2013 Society of Chemical Industry

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
