摘要： Microbial fuel cell (MFC) is a promising technology to generate bioelectricity from biomass feedstocks at mild operating temperature and pressure conditions. Despite promising progress in MFC systems, their commercialization has been a major challenge, mainly due to the high cost of components, limited power generation, and lower efficiency. Thus, developing economically viable and environmentally benign electrode and membrane materials that would substantially reduce the manufacturing cost and boost the performance of MFC systems is crucial. Hence, this review aims to highlight the opportunities of using abundantly available waste biomass resources to address the challenges of economic viability and low power productivity of MFC systems. In this stride, the potential of utilization of biomass waste as membrane constituents, electrode materials, and feedstock sources that would enable large-scale commercialization of MFC systems is discussed. Moreover, the study also reviews recent advances in systematic power management and optimization techniques to boost the overall power productivity and efficiency of MFC systems. Based on the comprehensive review made, it is observed that converting biomass waste resources to biochar or activated carbon for direct application as an electrode or electrode coating can decrease its cost by up to 90%. Furthermore, waste biomass-derived biochar can significantly lower the manufacturing costs of the membrane by up to 39 times. The optimum power management configurations are also proposed based on the analysis of the key factors, including the ability to boost low or ultra-low input voltage, the amount of output voltage, and the charging rate. The challenges and limitations of using waste biomass resources in MFC systems are outlined to enlighten future research directions in this domain.
