| Research Abstract |
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.
