Development of a hybrid microbial fuel cell (MFC) and fuel cell (FC) system for improved cathodic efficiency and sustainability: The M2FC reactor
چکیده انگلیسی

In an effort to improve the efficiency and sustainability of microbial fuel cell (MFC) technology, a novel MFC reactor, the M2FC, was constructed by combining a ferric-based MFC with a ferrous-based fuel cell (FC). In this M2FC reactor, ferric ion, the catholyte in the MFC component, is regenerated by the FC system with the generation of additional electricity. When the MFC component was operated separately, the electricity generation was maintained for only 98 h due to the depletion of ferric ion in the catholyte. In combination with the fuel cell, however, the production of power was sustained because ferric ion was continually replenished from ferrous ion in the FC component. Moreover, the regeneration process of ferric ion by the FC produced additional energy. The M2FC reactor yielded a power density of up to 2 W m−2 (or time-averaged value of approximately 650 mW m−2), density up to 20 times (or approximately six times based on time-averaged value) higher than the corresponding MFC system.


► To improve the efficiency and sustainability of MFC technology.
► The M2FC was constructed by combining a ferric-based MFC and ferrous-based FC.
► In M2FC, ferric ion was the catholyte in the MFC component.
► It is regenerated by the FC system with the generation of additional electricity.
