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

https://techxplore.com/news/2023-05-carbon-based-cathodes-impact-biofilm-composition.html

"SMFCs utilize endogenous microorganisms present in contaminated soil convert organic matter into electricity... carbon cloth, Pt-doped carbon cloth, graphite felt, and Fe-doped carbon nanofiber electrode... Fe-doped carbon nanofibers and Pt-doped carbon cloth cathodes stable peak power densities 25.5 and 30.4 mW m−2... Graphite felt cathodes best electrochemical performance but greatest instability... low-cost high-performing energy harvesting and bioremediation"
