Şeffaf bir PEM Yakıt Hücresinin Performansının Değerlendirilmesi

Bu çalışmada PEM yakıt hücresinin katot gaz akış kanalında oluşan sıvı su damlacıklarını gözlemlemek için bir tarafı şeffaf olan bipolar plaka tasarımı yapılmıştır. Katot gaz akış kanalının şeffaf olarak imal edilmesi yakıt hücresi içinde oluşan su damlacığının gözlemlenebilmesini mümkün kılacaktır. İmalatı yapılan bipolar plaka malzemesinin gözlem imkanı sağlamasının yanı sıra elektron iletimini de sağlaması gerekmektedir. Bu yüzden; şeffaf yakıt pili oluşturmak için 1 mm kalınlığında saç levha üzerine kanal tasarımı imal edilmiş ve saç levha üzerine 10 mm kalınlığında polikarbonat levha monte edilmiştir. Şeffaf olarak imal edilen yakıt pili deneysel performans sonuçları alüminyum levha üzerine imal edilen kanal tasarımının deneysel performans sonuçlarıyla kıyaslanmıştır. Sonuç olarak, kanal içeresindeki sıvı su oluşumunu gözlemlemek isteyen araştırmacılara şeffaf bipolar plaka imalatı ve imal edilen bipolar plakaların deneysel performansı hakkında çıkarımlarda bulunulmuştur.
