Recently microbial fuel cells (MFCs) have attracted increasing interests in both environmental and energy fields. Among the various MFC configurations, miniature microbial fuel cell (mini-MFC) has a great potential for the application in medical, communication and other areas because of its miniature volume and high output power density. In this work, a 25-μL single-chamber mini-MFC was fabricated using the photolithography technique. The plate-shaped gold anodic electrode in the mini-MFC showed a higher electrochemical activity than the stripe-shaped one. A biofilm of Shewanella oneidensis MR-1 was formed on the surface of gold electrode in this micro-liter-scale MFCs. As a result, a maximum power density of 29 mW/m(2) and a maximum current density of 2148 mA/m(2) were achieved by this single-chamber mini-MFC.
最近，微生物燃料电池（MFCs）在环境和能源领域引起了越来越多的关注。在各种 MFC 配置中，由于其体积小、输出功率密度高，微型微生物燃料电池（mini-MFC）在医学、通信等领域具有很大的应用潜力。在这项工作中，使用光刻技术制造了一个 25μL 的单室 mini-MFC。在 mini-MFC 中，板状金阳极电极的电化学活性高于条状金阳极电极。在这个微升规模的 MFC 中，Shewanella oneidensis MR-1 的生物膜形成在金电极的表面。结果，这个单室 mini-MFC 实现了 29 mW/m(2) 的最大功率密度和 2148 mA/m(2) 的最大电流密度。
