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.
