摘要: | 在現今的社會,石化燃料仍然是全球使用率最高的能源之一,然而,這些能源並不是無窮無盡。在國際的能源峰會上,各國也努力找出石化能源的代替且可行方案,減少我們對化石燃料的過度依賴。植物微生物燃料電池(Plant microbial fuel cell, PMFC)作為近年來的一種新興的綠色能源,籍由植物進行光合作用,根系產生根際分泌物,土壤中微生物以其作為養份源來產生電子結合電極系統,最終透過植物將太陽能轉換為電能,為解決我們對化石燃料的依賴提供了其中一個替代能源。 本研究以植物微生物燃料電池作為研究對象,利用不同的基礎電路組合—串聯及並聯,並結合城市綠屋頂的概念,評估植物在不同天氣下的生長對微生物發電的影響,以及在長時間連續輸出電壓的穩定性。從結果顯示,串聯及並聯電路之PMFC系統產生之電壓相比起土壤微生物燃料電池(Soil microbial fuel cell, SMFC)有明顯的上升趨勢,但穩定性相對較低;其中對於單日最大平均輸出電壓,八個串聯電路之PMFC系統相比八個並聯電路之PMFC系統更高出二倍的電壓輸出,分別為1.213 V和0.581 V,其電功率密度分別為2.94 mWm-2和0.67 mWm-2;另外在48小時的充電試驗中,八個串聯電路及八個並聯電路之PMFC系統可為電容充電至4.8 V及1.5 V。從上述之結果均反映了串聯電路具有較好之發電潛力。 Nowadays, fossil fuels are the most commonly used energy sources in the world; however, these energy sources are not endless. At international energy summits, countries are also looking for alternative and feasible solutions to displace fossil fuels in order to reduce our excessive dependence on it. Plant microbial fuel cell (PMFC) is an emerging green energy source in recent years. Microorganisms in soil use photosynthesis of plants and production of rhizosphere exudate by roots as a nutrient source to produce electrons and bind electrodes which finally converts solar energy into electricity through plants, providing one of the alternative energy sources to solve our dependence on fossil fuels. This research uses PMFCs as the target, utilizing different basic circuit combinations—series and parallel connection, and combines the concept of urban green roofs to evaluate the impact of plant growth on microbial power generation, and its stability in different weathers and to continuously measure the output voltage for a long time. The results show that the voltage generated by the PMFC system of series and parallel circuits has a significant upward trend compared with the soil microbial fuel cell (SMFC), but the stability is relatively low; Compared with the PMFC system with eight parallel circuits, the average maximum output voltage of the day of the PMFC system with eight series circuits has twice the voltage output of 1.213 V and 0.581 V respectively in a single day, and its electric power density is 2.94 mWm-2 and 0.67 mWm-2 respectively; In the 48-hour charging test, the PMFC system with eight series circuits and eight parallel circuits charged the capacitors to 4.8 V and 1.5 V. The above results all reflect the potential power generation of the series circuit. |
