Measurement of the behavior of plugging water in a practical PEFC using a visualization cell with three pinpoint windows

聚合物电解质燃料电池（PEFC）存在水管理问题，例如水淹（冷凝液阻塞气体扩散层的孔隙）和堵塞（冷凝液阻塞气体通道）。我一直在开发一种高性能分离器。与固体壁电池（标准电池）相比，透明壁电池的性能较差。本研究利用具有三个精确窗口的可视化单元阐明了实际PEFC中堵塞水的行为。此外，我将高性能分离器应用于PEFC的阴极侧，并通过使用可视化技术评估了其有效性。

Polymer electrolyte fuel cell (PEFC) has water management issues, such as flooding, where condensate blocks the pores of the gas-diffusion-layer, and plugging, where condensate blocks the gas channels. I have been developing a high performance separator. Cell performance of the clear-walled cell was poor when compared to that of the solid-walled cell (the standard cell). This study elucidated the behavior of the plugging water in a practical PEFC using a visualization cell with three pinpoint windows. Moreover, I applied the high performance separator to the cathode side of a PEFC and evaluated the effectiveness by using a visualization technique.
