Research progress of magnetic materials in microbial fuel cell applications

Abstract

Abstract As a new type of environmental protection technology that can treat sewage and generate electricity, microbial fuel cells (MFC) have broad research prospects. In recent years, MFC has made great breakthroughs, but its high internal resistance and low power generation efficiency have prevented its development. Researchers began to study the influence of magnetic fields on the MFC power generation efficiency to improve the power generation efficiency, and the results are gratifying. This shows that magnetic materials may be the solution to push MFC to practical applications. This article briefly introduces the research progress of magnetic materials as the additional structure of MFC and MFCs electrode materials, and discusses the role and influence of magnetotactic bacteria in MFC.
