Abstract

This study compared the performance of microbial fuel cells (MFCs) using parchment paper as a separator to a CMI7000 proton exchange membrane. The MFCs were operated in two chambers with whey solution as the substrate. Parameters such as COD removal, internal resistance, power density, current density, and Coulombic efficiency ratio (CE) were evaluated. The CMI7000 membrane exhibited the highest COD removal at 92%, while the parchment paper achieved removal percentages ranging from 72 to 91%. The internal resistance was lower for the parchment paper separator for the first run, the internal resistances were 68 Ώ and 84 Ώ for parchment paper and CMI7000, respectively. The maximum energy densities were 219 mW/m² (5.74 mA/m²) and 421 mW/m² (8.24 mA/m²) for parchment paper and CMI7000 membrane, respectively. The CE values for parchment paper were 36.32% and 33.5%, while for the CMI7000 membrane, they were 42.73% and 32.0%, for the two runs. Overall, the study demonstrated that the parchment paper separator performed reasonably well in terms of COD removal, internal resistance, energy density, and Coulombic efficiency ratio compared to the CMI7000 membrane in microbial fuel cells.

用于微生物燃料电池中奶酪乳清处理的低成本新型分离器的羊皮化工艺

摘要本研究比较了使用羊皮纸作为隔膜的微生物燃料电池（MFC）和 CMI7000 质子交换膜的性能。MFC 以乳清溶液为基质，在两个腔室中运行。对 COD 去除率、内阻、功率密度、电流密度和库仑效率比 (CE) 等参数进行了评估。CMI7000 膜的 COD 去除率最高，达到 92%，而羊皮纸的去除率则从 72% 到 91% 不等。在第一次运行中，羊皮纸分离器的内阻较低，羊皮纸和 CMI7000 的内阻分别为 68 Ώ 和 84 Ώ。羊皮纸和 CMI7000 薄膜的最大能量密度分别为 219 mW/m2（5.74 mA/m2）和 421 mW/m2（8.24 mA/m2）。羊皮纸的 CE 值分别为 36.32% 和 33.5%，而 CMI7000 膜的 CE 值分别为 42.73% 和 32.0%。总之，研究表明，与微生物燃料电池中的 CMI7000 膜相比，羊皮纸分离器在化学需氧量去除率、内阻、能量密度和库仑效率比等方面的表现都相当不错。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
