Éó¸åÈ˸ø³öµÄÒ»ÌõÒâ¼û£º¡°The optimized pore structures in the catalyst layers are effective to reduce the mass transport losses. However, large pore structures generally have negative aspects that the proton conductivity is reduced and the electrical resistance is increased. The cell performance was varied depending on the various losses caused by ohmic, activation and concentration overpotentials.the authors should demonstrate detailed reasons why the pore structures in the catalyst layers reduced the overpotentials, and thereby enhanced the cell performance.¡± ÎÄÕÂÖÐÓÐEISͼÆ×£¬ÇëÎÊÊÇÒª×ÛºÏÅ·Ä·×迹ºÍ»î»¯×迹¶Ôµç³ØÐÔÄܵÄÓ°ÏìÂ𣿻¹ÊÇ´ÓÆäËüµÄ½Ç¶È½øÐнâÊÍ£¿ ´ËÍ⣬concentration overpotentials·½ÃæÈçºÎ½øÐвûÊÍ£¿ ·Ç³£¸Ðл£¡ |
