Abstract

Ethanol emerges as an alternative fuel since it has higher energy density, less toxic in nature, easy availability and can be produced from biomass. The passive Direct Ethanol Fuel Cell (DEFCs) has good potential to fulfill the power requirements of portable applications compared to methanol. However passive DEFCs are far away from acceptable power outputs due to their slow ethanol oxidation reaction and ethanol and water crossover. In this study a passive DEFC was design and fabricated. The 115 Nafion membrane with active area of 25cm2 was used to identify the optimal working condition for ethanol feed concentration and cell orientations. It was found that 4M ethanol feed concentration gives optimal cell performance. It is observed that open circuit voltage (OCV) was independent of the cell orientation but it is affected by the ethanol feed concentration. The cell performance is also tested on cell orientation. Horizontal orientation yielded better performance compared to vertical orientation.

乙醇浓度和电池取向对被动直接乙醇燃料电池性能的影响

乙醇作为一种替代燃料出现，因为它具有更高的能量密度，本质上毒性较小，易于获得并且可以从生物质中生产。与甲醇相比，被动直接乙醇燃料电池(defc)在满足便携式应用的功率要求方面具有良好的潜力。然而，由于其缓慢的乙醇氧化反应和乙醇与水的交叉，被动defc远离可接受的功率输出。本研究设计并制作了被动式DEFC。采用活性面积为25cm2的115 Nafion膜确定乙醇饲料浓度和细胞取向的最佳工作条件。结果表明，乙醇饲料浓度为4M时，细胞性能最佳。开路电压(OCV)与细胞取向无关，但受乙醇浓度的影响。电池的性能也在电池方向上进行了测试。水平取向比垂直取向产生更好的性能。
