Improvement of microbial fuel cell performance using novel kaolin earthenware membrane coated with a polybenzimidazole layer

Abstract A proton exchange membrane (PEM) is one of the most critical and expensive components in a dual‐chamber microbial fuel cell (MFC) that separates the anode and cathode chambers. The novel macroporous kaolin earthenware coated with polybenzimidazole (NKE‐PBI) fabricated in this study could be...
