Improved performance of microbial fuel cell using membrane-electrode assembly

Abstract

A mediator-less microbial fuel cell (MFC) was used to determine the performance effects of a membrane-electrode assembly (MEA). The MFC with an MEA generated a higher current with an increased coulomb yield when compared to an MFC with a separate cathode. Less oxygen was diffused through an MEA than through a Nafion membrane. The MFC performance was improved with a buffer, although a high-strength buffer reduced the performance.
