碩士 === 國立中興大學 === 精密工程學系所 === 97 === The goal of this research is to develop a portable yeast microbial fuel cell system and enhance its performance. Such developed system can be further applied to drive the mini-scale electronic devices. The anode of microbial fuel cell includes the yeast as the catalyst. Through chemical reactions, glucoses are decomposed and produce the electrical energy. Methylene blue is used as the electron transfer mediator. Vitamin K3 can increase oxidation and reduction efficiency. The complete single cell voltage is 0.55 volts and the maximum power density is 0.35mW/cm3. Furthermore, the fuel cell stack of 4 units in series has an overall potential over 2.15 volts. It’s built and successfully to light a LED for practical power generation.
