“…The results show that the distribution of PTFE and the existence of binder have great influence on the removal rate of water droplets in gas diffusion layer. The second is to artificially process the route of liquid water to break through the gas diffusion layer by drilling, so as to reduce the water distribution in the gas diffusion layer 20‐23 . Niu et al 24 carried out numerical simulation about the fluid water movement in the perforated GDL via VOF method.…”

“…The second is to artificially process the route of liquid water to break through the gas diffusion layer by drilling, so as to reduce the water distribution in the gas diffusion layer. [20][21][22][23] Niu et al 24 carried out numerical simulation about the fluid water movement in the perforated GDL via VOF method. The result shows that perforating can markedly reduce the liquid level and oxygen transport resistance in the GDL.…”

“…Ghasemi ve arkadaşları yakıt pillerinde su yönetiminin performans açısından çok önemli olduğunu belirtmişlerdir [4].Carton ve arkadaşları PEM yakıt pilleri için su taşmasını içeren detaylı bir literatür taraması yapmış, gaz difüzyon tabakası ile damlacık oluşumu, hareketi ve etkileşimi kapsamlı olarak incelenmiştir [5]. Lee ve arkadaşları düşük sıcaklıkta çalışan PEM yakıt pillerinde yoğunlaşan suyun katalizör tabakası ve gaz difüzyon tabakasından uzaklaştırmanın zor olduğunu belirterek şeffaf olarak tasarladıkları yakıt pili ile bazı denemeler yapmışladır [6]. Aslam ve arkadaşları su taşması ve membran kurumasının PEM yakıt pillerinin performansını ve dayanıklılığını etkileyen iki ana unsur olduğunu vurgulamışlardır [7].…”
