Commercial fluorine-based membranes, which are mainly used as proton exchange membranes for microbial fuel cells, have low durability and high prices, so they have a problem of poor economic feasibility. In the microbial fuel cell system, organic material loss and cathode contamination problems occur due to the crossover phenomenon in which organic materials penetrate the proton exchange membrane, and the probability for H+ ions to react with the ion transporter of the proton exchange membrane is reduced. Therefore, in this study, in order to replace the expensive fluorine-based membrane, a partially fluorine-based composite membrane with ion conductivity was prepared by impregnating the pores inside and on both sides of the microporous nanofiber substrate with a sulfonated hydrocarbon-based polymer electrolyte. In addition, this partial fluorine-based composite membrane was applied to a microbial fuel cell and its characteristics were studied. |
