Carbon-based cathodes impact biofilm composition and performance in soil microbial fuel cells

Researchers found that Fe-doped carbon nanofibers and Pt-doped carbon cloth cathodes yielded stable performances, with peak power densities of 25.5 mW m−2 and 30.4 mW m−2, respectively. Graphite felt cathodes demonstrated the best electrochemical performance but exhibited lower reproducibility and higher mass transport losses.
