摘要翻译：
12个单室空气阴极管式微生物燃料电池（TMFCs）被装满水果和蔬菜残渣。阳极是通过碳纤维刷实现的，阴极是通过带有Nafion膜的石墨基多孔陶瓷盘（117杜邦）实现的。根据不同的操作条件：固体基质水的稀释率、淡水和35mg/L NaCl水溶液的使用以及初始恒电位生长的影响，对其极化曲线和功率生产性能进行了评价。所有的TMFCs都在低pH下运行(pH$=3.0\PM0.5$),因为没有进行pH修正。尽管在恶劣的环境条件下，我们的TMFCs的功率密度(PD)范围为20～55mW/m$^2Cdot$kg$_{text{wast}}$,阴极表面的最大CD为20mA/m$^2Cdot$kg$_{text{wast}}$。COD去除在$28-$1天期间大约是$45\%$。低pH值以及Nafion膜的污染很可能限制了TMFC的性能。然而，与实际的厌氧消化工厂相比，我们的反应器的放大估计在功率生产方面提供了有趣的价值。这些结果鼓励进一步研究石墨基多孔陶瓷阴极的特性和优化TMFC的整体性能，因为它们可能提供一种有效和可持续的厌氧消化技术的替代方案。

英文摘要：
  Twelve single chambered, air-cathode Tubular Microbial Fuel Cells (TMFCs) have been filled up with fruit and vegetable residues. The anodes were realized by means of a carbon fiber brush, while the cathodes were realized through a graphite-based porous ceramic disk with Nafion membranes (117 Dupont). The performances in terms of polarization curves and power production were assessed according to different operating conditions: percentage of solid substrate water dilution, adoption of freshwater and a 35mg/L NaCl water solution and, finally, the effect of an initial potentiostatic growth.   All TMFCs operated at low pH (pH$=3.0 \pm 0.5$), as no pH amendment was carried out. Despite the harsh environmental conditions, our TMFCs showed a Power Density (PD) ranging from 20 to 55~mW/m$^2 \cdot$kg$_{\text{waste}}$ and a maximum CD of 20~mA/m$^2 \cdot$kg$_{\text{waste}}$, referred to the cathodic surface. COD removal after a $28-$day period was about $45 \%$.   The remarkably low pH values as well as the fouling of Nafion membrane very likely limited TMFC performances. However, a scale-up estimation of our reactors provides interesting values in terms of power production, compared to actual anaerobic digestion plants. These results encourage further studies to characterize the graphite-based porous ceramic cathodes and to optimize the global TMFC performances, as they may provide a valid and sustainable alternative to anaerobic digestion technologies.
