    摘要註: 許多微生物(如藻類或細菌)擁有產生氫氣的能力,藉由微生物燃料電池可以直接將衣藻產生的氫氣及代謝過程中傳遞的電子轉換成能量,具有吸收二氧化碳、成本低和受環境影響小等優點。然而此技術的關鍵在於微生物與電極之間的固定效果及催化作用。本論文研製於利用藻類拓印高分子的方法,以不同重量百分濃度之38mol%乙烯乙烯醇共聚合物為拓印材料,將模版塗佈於電極上並分析其薄膜性質,進而應用在微生物燃料電池中,量測其電化學性質,同時研究受到模版固定後之衣藻生物體內分子及氫化酶基因表現的變化。最後發現5、7和10 wt%之藻類模版有密度高且清晰的衣藻孔洞,並且於微生物燃料電池中7 wt%有最佳效果,將最大功率由0.7提升至1.8 mW/m2,約提高了2.6倍。衣藻在受藻類模版固定後也發現氫化酶基因表現量約增加了1.15倍,表示衣藻拓印高分子電極可能誘導衣藻產生較多的氫氣,也可能為使電池效能提升的原因之一。 Hydrogen can be produced using microorganisms (e.g., bacteria and algae). The direct conversion of hydrogen and the transferred electrode of metabolism to electricity via microbial fuel cells (MFCs) may be a lot of benefit such as carbon dioxide fixation, low cost and little affected by environment. However, the key point of the technology is the immobilization and catalysis between microbes and electrodes. In this work, the different weight % of 38mol% poly(ethylene-co-vinyl alcohol)(EVAL), was coated on the electrode, and green algae was microcontact imprinted onto the EVAL film(algae imprinted polymer, AIP). The character of film have been analyzed by Scanning electron microscopy(SEM) and Energy-dispersive X-ray spectroscopy (EDX). The application of AIP electrodes in MFC is the second study. Their electrochemical character has analyzed by Potentiostat. The complex in algae body and hydrogenase gene expression has also been studied. Finally, there are high density and clear image of cavities on 5, 7 and 10 wt% AIP electrodes. 7 wt% AIP electrodes was the best effect in MFC. It enhanced the maximum power from 0.7 to 1.8 mW/m2. It's around 2.6 fold. Furthermore, the expression of hydrogenase gene increased 1.15 fold after algae immobilized on AIP electrode. It shows AIP electrode can induce hydrogen production of algae and that may be one of the reasons of efficiency increasing in MFC.
