A novel and robust distributed benthic microbial fuel cell (DBMFC) was developed to address the energy supply issues for oceanographic sensor network applications, especially under scouring and bioturbation by aquatic life. Multi-anode/cathode configuration was employed in the DBMFC system for enhanced robustness and stability in the harsh ocean environment. The results showed that the DBMFC system achieved peak power and current densities of 190mW/m(2) and 125mA/m(2) respectively. Stability characterization tests indicated the DBMFC with multiple anodes achieved higher power generation over the systems with single anode. A computational model that integrated physical, electrochemical and biological factors of MFCs was developed to validate the overall performance of the DBMFC system. The model simulation well corresponded with the experimental results, and confirmed the hypothesis that using a multi anode/cathode MFC configuration results in reliable and robust power generation.
一种新颖而强大的分布式底栖微生物燃料电池（DBMFC）被开发出来，以解决海洋传感器网络应用的能源供应问题，特别是在水下生物冲刷和生物扰动的情况下。多阳极/阴极配置被应用于 DBMFC 系统中，以增强在恶劣海洋环境中的鲁棒性和稳定性。结果表明，DBMFC 系统分别实现了 190mW/m(2)和 125mA/m(2)的峰值功率和电流密度。稳定性特征测试表明，多阳极的 DBMFC 比单阳极的系统产生更高的发电量。开发了一个综合 MFC 物理、电化学和生物因素的计算模型，以验证 DBMFC 系统的整体性能。模型模拟与实验结果非常吻合，证实了使用多阳极/阴极 MFC 配置可实现可靠和强大的发电的假设。
