Proton Değişim Membran Yakıt Hücresinin (PDMYH) Hücre Bazlı Deneysel Analizi

Bu çalışma, sodyum borhidrür (NaBH4) kullanılan bir proton değiştirme membranı (PEM) yakıt pilinin hücre bazlı deneysel analizi üzerine odaklanmıştır. NaBH4, saf su ve katalizör olarak kullanılan sitrik asit (C6H8O7) sabit yükte tutularak iki farklı sıcaklıkta 10 hücreli PEM yakıt pilinin hücre bazlı gerilim değerlerindeki değişim değerlendirilmiştir. 3 g NaBH4, H2O/NaBH4: 2 mol/mol (x=0) ve C6H8O7 katalizörü/NaBH4: 0.1 g/g ile 250 cm3 reaktör hacminde hidrojen üretimi gerçekleştirilmiştir. Su sıcaklığı 40 ºC’den 60 ºC’ye çıkarıldığında toplam gerilim değeri % 6.1 oranında artmıştır. 40 °C deneyinde ortalama gerilim değerleri 0.53 V ila 0.78 V arasında değişirken 60 °C deneyinde ise ortalama değerler 0.61 V ila 0.79 V arasında değişmiştir.

Cell-Based Experimental Analysis of a Proton Exchange Membrane Fuel Cell (PEMFC)

This study is focused on cell-based experimental analysis of Proton Exchange Membrane Fuel Cell (PEMFC) withsodium borohydride (NaBH4). The change in cell-based voltage values of 10-cell PEM fuel cell at two differenttemperatures was evaluated by keeping at constant load NaBH4, pure water and citric acid (C6H8O7) which is usedas a catalyzer. 3 g NaBH4, H2O/NaBH4: 2 mol/mol (x=0), and C6H8O7 catalyzer/NaBH4: 0.1 g/g and 250 cm3 ofreactor volume production were realized. When the water temperature was raised to 60 ºC from 40 ºC, total voltagevalue increased by 6.1%. While, in the experiment of 40 ºC, the interchange in voltage values were between 0.53V and 0.78 V, the mean values in the experiment of 60 ºC were between 0.61 V and 0.79 V.
