Impact of anode surface modifications on microbial fuel cell performance and algal biomass production.

In this study, the performance of dual-chamber microbial fuel cells with carbon fiber (CF) anodes surface modified by multi-walled carbon nanotube coating (CF-MWCNT) and nitric acid treatment (CF-HNO) was compared. The performance of all these modified anodes was found to be better than bare electrode. The modified anodes were shown to significantly outperform the bare electrode anodes.
