摘要

微生物燃料电池是一种利用电活性细菌作为催化剂的生物电化学反应，产生电能并清理污水的技术，被认为是一种可持续发展的技术。本文研究了不同开路电位时间对堆肥渗滤液产生电流密度的影响。结果表明，利用堆肥渗滤液制备出电活性生物膜，电势为-0.2V/ESC。在28天的开路持续时间后，极化仅3h就达到了最大电流密度(458.3µA/cm²)。利用扫描电子显微镜对碳石墨电极在不同阶段形成的生物膜进行了表征。

Effects of Open Circuit Potential and Characterization of Electro-Active Biofilm for Microbial Fuel Cells using Compost Leachate

A microbial fuel cell produce electric energy and clean up effluents thanks to bio-electrochemical reactions in which electro-active bacteria are used as catalysts, it is considered as a sustainable technique. This paper focuses on the effect of different times of open circuit potential on the current density produced by compost leachate. The obtained results demonstrate that an electro-active biofilm was developed using compost leachate, with a potential (-0.2V/ESC. Maximum current density (458.3 µA/cm²) was reached after only 3h of polarization after an open circuit duration of 28 days. Scanning electron microscopy has been used to characterize the biofilm formed on carbon graphite electrodes at different phases.

期刊介绍： The International Journal of Renewable Energy Research (IJRER) is not a for profit organisation. IJRER is a quarterly published, open source journal and operates an online submission with the peer review system allowing authors to submit articles online and track their progress via its web interface. IJRER seeks to promote and disseminate knowledge of the various topics and technologies of renewable (green) energy resources. The journal aims to present to the international community important results of work in the fields of renewable energy research, development, application or design. The journal also aims to help researchers, scientists, manufacturers, institutions, world agencies, societies, etc. to keep up with new developments in theory and applications and to provide alternative energy solutions to current issues such as the greenhouse effect, sustainable and clean energy issues.
