Abstract

In this study, microbial fuel cells were designed using E. aerogenes, an importantproton producing bacterium, to determine energy efficiency. In the design of these fuelcells, nafion membrane is preferred as a proton permeable membrane. Potassiumferricyanide was used in the cathode section when the anode partition mediator wasprefered as methylene blue. Within the scope of the study, the efficiency of theelectrode route on the optimization and energy efficiency of fuel pellets prepared usingE. aerogenes was determined. A comparative study was carried out using graphite,composite and copper electrodes as the electrode type. In the experiment with copperelectrode, the highest voltage value was read as 0.23 V, 0.38 V on the compositeelectrode and 0.52 V on the carbon electrode. It is determined that the electrode givingthe highest voltage is the carbon electrode. Furthermore, optimization of designedmicrobial fuel cell’s nutrient, pH and microorganism incubation time has been realized.

Özet

Bu çalışma kapsamında önemli bir proton üreten bakteri türü olan E. aerogenes kullanılarak mikrobiyal yakıt hücreleri tasarımı gerçekleştirilerek enerji verimlilikleri belirlenmiştir. Bu yakıt hücrelerinin tasarımında proton geçirgen membrane olarak nafyon membran tercih edilmiştir. Anot bölmesi medyatörü metilen mavisi olarak tercih edilirken katot bölmesinde Potasyum ferrisiyanid kullanılmıştır. Çalışma kapsamında E. aerogenes kullanılarak hazırlanan yakıt pillerinin optimizasyonu ve enerji verimliliği üzerine elektrot türünün etkinliği belirlenmiştir. Elektrot türü olarak grafit, alaşım ve bakır elektrotlar kullanılarak kıyaslamalı bir çalışma gerçekleştirilmiştir. bakır elektrotla yapılan denemede en yüksek voltaj değeri 0.23 V, kompozit elektrotda 0.38 V, karbon elektrotta ise 0.52 V olarak okunmuştur. En yüksek voltaj miktarını veren elektrotun karbon elektrot olduğu saptanıştır. Ayrıca hazırlanan mikrobiyal yakıt pilinin, besiyeri, pH ve mikroorganizma inkübasyon süre optimizasyonları gerçekleştirilmiştir.
