Abstract Microbial fuel cells (MFCs) can be used to produce clean energy from organic wastes. Various biomasses for MFCs can be used as biofuel materials. Moss (Bryophyta) is a source of biomass materials and can be used as an alternative fuel for microbial fuel cells. In this study, moss-enriched MFCs were produced by using moss as a biofuel source and aluminum and silver as an electrode. As a result of the good electrochemical performance of the metal electrodes (aluminum and silver), higher power density than previous studies involving moss was obtained, with the highest power density in this study being 20 mW/m2. Moreover, in this study, bacterial activity, biofilm formation, soil utilization, pH change, and corrosion were investigated in MFCs and the effects of MFC on power density were discussed. The addition of soil increased the corrosion rate and internal resistance while reducing the power density. As a result of the addition of soil, the power density dropped to 16.13 mW/m2. The corrosion rate was lower than industrial corrosion. Changes in pH confirmed that organic material dissolved and chemical reactions took place. Scanning electron microscope (SEM)-Energy dispersive spectroscopy (EDS) analyzes showed the presence of Bacillus and Coccus bacteria species on the electrode surfaces. These bacteria were acted as biocatalysts by forming a biofilm on the electrode surfaces.

高效环保富苔藓微生物燃料电池

摘要 微生物燃料电池（MFCs）可用于从有机废物中生产清洁能源。用于 MFC 的各种生物质可用作生物燃料材料。苔藓（苔藓植物）是生物质材料的来源，可用作微生物燃料电池的替代燃料。在这项研究中，使用苔藓作为生物燃料来源，铝和银作为电极，生产富含苔藓的 MFC。由于金属电极（铝和银）的良好电化学性能，获得了比之前涉及苔藓的研究更高的功率密度，本研究中的最高功率密度为 20 mW/m2。此外，在本研究中，研究了 MFC 中的细菌活性、生物膜形成、土壤利用、pH 变化和腐蚀，并讨论了 MFC 对功率密度的影响。土壤的添加增加了腐蚀速率和内阻，同时降低了功率密度。由于添加了土壤，功率密度下降到 16.13 mW/m2。腐蚀速率低于工业腐蚀。pH 值的变化证实有机物质溶解并发生化学反应。扫描电子显微镜 (SEM)-能量色散光谱 (EDS) 分析显示在电极表面上存在芽孢杆菌和球菌。这些细菌通过在电极表面形成生物膜来充当生物催化剂。pH 值的变化证实有机物质溶解并发生化学反应。扫描电子显微镜 (SEM)-能量色散光谱 (EDS) 分析显示在电极表面上存在芽孢杆菌和球菌。这些细菌通过在电极表面形成生物膜来充当生物催化剂。pH 值的变化证实有机物质溶解并发生化学反应。扫描电子显微镜 (SEM)-能量色散光谱 (EDS) 分析显示在电极表面上存在芽孢杆菌和球菌。这些细菌通过在电极表面形成生物膜来充当生物催化剂。
