The present research deals with the development of Solid Phase Microbial Fuel Cell (SMFC) using the organic wastes and their admixture in the presence of 0.01% fulvic acid. The organic wastes such as fallen leaves (FL), bamboo waste (BW), leaf mould (LM), rice bran (RB) and fulvic acid (FA) were used during the operation of SMFC. The anode and cathode materials were bamboo carbon (with iron winding) and granular activated carbon respectively. The study explored the possibilities of generating power due to the microbial degradation of chosen organic wastes and their admixtures. The polarization curves were plotted with the current – voltage and current – power characteristics for the influence of organic wastes and the admixtures in the presence of fulvic acid. The maximum electrical power of 1071 mWm⁻² was generated using the organic admixture containing BW, LM and RB in the presence of FA. The SMFC with different admixtures corroborated the microbial degradation of organic compounds and the subsequent power generation with respect to days. The admixture used in the SMFC was proved very effective as compost in growing Komatsuna seeds with a scope for recycling and zero disposal. The Electrochemical Impedance Spectroscopy study corroborated the influence of admixture compositions in the variation of resistance values. The characterization studies such as SEM (with EDS), FTIR, Raman and BET studies corroborated the changes caused to the surface of the bamboo carbon anode. The cost analysis confirmed that the fabrication of SMFC unit is inexpensive thanks to the consumables from sustainable sources.

本研究涉及在 0.01% 富里酸存在下使用有机废物及其混合物开发固相微生物燃料电池 (SMFC)。SMFC运行过程中使用了落叶（FL）、竹屑（BW）、叶霉（LM）、米糠（RB）和富里酸（FA）等有机废物。正负极材料分别为竹炭（铁缠绕）和颗粒活性炭。该研究探索了由于选定的有机废物及其混合物的微生物降解而发电的可能性。极化曲线与电流-电压和电流-功率特性一起绘制，用于在富里酸存在下有机废物和混合物的影响。最大电功率 1071 mWm ⁻²使用含有 BW、LM 和 RB 的有机混合物在 FA 存在下产生。具有不同混合物的 SMFC 证实了有机化合物的微生物降解和随后的发电量。事实证明，在 SMFC 中使用的混合物作为堆肥非常有效，可用于种植 Komatsuna 种子，并具有回收和零处理范围。电化学阻抗谱研究证实了混合物成分对电阻值变化的影响。SEM（带有 EDS）、FTIR、拉曼和 BET 研究等表征研究证实了对竹炭阳极表面造成的变化。成本分析证实，由于消耗品来自可持续来源，SMFC 装置的制造成本低廉。
