陰極波浪型流道對質子交換膜燃料電池性能之影響
Effect of Cathode Wavy Channel on the Performance of PEMFC
摘要
本研究以熱固性酚醛樹脂20% 和石墨80% 均勻混合後再熱壓成平板，最後利用銑床在平板上刻劃流道完成雙極板。並藉由設計波浪形流道與改變流道深淺等因素，來探討對質子交換膜燃料電池之影響。 流道雙極版設計直接影響質子交換膜燃料電池之性能表現，在不同流道形狀，及流道排列組合下，對電池功率表現也會有所不同。本實驗探討在固定陽極流道形狀下，改變陰極流道形狀以及改變不同流道深度做比較。 實驗結果顯示在流道深度皆為1.0mm的條件下，以直通平行流道加入波型幾何結構的直通波形流道，能有效提升單電池之性能。而在改變流道深淺的條件下，流道深度較淺之雙極板能有效提升單電池之性能，並使直通波型流道與平行蛇型流道性能相近。而流道深度的增加則使單電池性能降低。

In this study, plate have 20% thermoset phenolic resin and 80% graphite were uniformly mixed and then heat pressing. Finally, channel of bipolar plate be carved by LNC(milling machine). Investigate the effect of PEMFC (proton exchange membrane fuel cell) by different type of channel and different depth. The channel type of bipolar plate directly affects on the performance of PEMFC, including the array of channel, the shape of channel, channel depth , ect. This study investigates at a fixed the channel type of anode with different shape of cathode channel and the depth of channel. Moreover, the results compare with Parallel three snakes runner. This result shows wavy-channel can enhance the performance of the single cell in the same depth or shallower depth. In addition, wavy-channel is better than straight channel on the performance of the single cell.
