| 中文摘要 | 在体积微型化条件下,极板流场图形的设计对燃料电池的性能优化,尤其是提高面积比功率,具有极其重要的意义.本文设计了不同沟道和沟脊宽度的阳极极板,测试了相应微型自吸氧燃料电池的性能变化.实验结果表明,在沟脊宽度小于沟道宽度的条件下,增加沟道或沟脊宽度都能改善微型燃料电池的性能,但改善幅度随宽度增加而趋缓.当沟道和沟脊宽度等比例变化时,性能随宽度的增加的最优值为600μm,其性能达到了2.87mW/cm2,优于沟道和沟脊均为400μm和800μm的燃料电池的性能.; The effect of anode flow pattern on the performance of micro air-breathing DMFC is investigated experimentally in this work. Single serpentine flow patterns with different channel and rib width were designed, fabricated and tested. The experiment results show that channel width increase will significantly improve the performance of a micro fuel cell. However, such influence fades as the channel is widening. The increase of the rib width can also improve the performance of micro fuel cell due to the melioration of current collection. Furthermore, there is an optimized width value while the channel width changes in proportion with the rib.; 国家自然科学基金资助项目(90607014) |
