“…As the figure shows, PEM fuel cells consist of nine different parts from the outside to the inside of fuel cell: the cathode current collector plate, cathode gas channel, cathode gas diffusion layer, cathode catalyst layer, membrane, anode catalyst layer, anode gas diffusion layer, anode gas channel, and anode current collector plate, respectively. The physical properties of the PEM fuel cell layers [19] and the thermophysical properties of the fluids [19] were selected in accordance with the literature and shown in Tables 2 and 3, respectively.…”

In this study, the effects of varying operating conditions on cell performance in cylindrical and planar PEM (Proton Exchange Membrane) fuel cells with equal geometrical properties are investigated numerically. For this purpose, planar and cylindrical fuel cells are analyzed and the changes in performance are compared with each other. In particular, by increasing the temperature from 363 to 373 K, the current density decreases by ≈50%. When the pressure is increased from 1 atm to 1.2 atm, the current density increases by 20% and 2% in cylindrical and planar fuel cells, respectively. When the stoichiometric ratio is increased from 1 to 1.5, the current density increases by 25% and 32% for cylindrical and planar fuel cells, respectively. However, it decreases slightly after 1.5 value of the stoichiometric ratio. As a result, it is seen that temperature has a more significant effect on fuel cell performance than other operating conditions. It can be said that the planar fuel cell can operate with more stable performance than the cylindrical fuel cell when the temperature and pressure are changed. However, in the case of changing the stoichiometric ratio, there is no significant difference in the operating performance of both fuel cells.

Günümüzde artan enerji talebinin büyük bir kısmı halen yüksek miktarda hidrokarbon içeren fosil yakıt kaynaklarından sağlanmaktadır. Bu durum hava kirliliği ve küresel ısınma gibi birçok çevresel probleme yol açmaktadır. Bu sorunlar karşısında tüm dünya yenilenebilir enerji kaynaklarına yönelik araştırma ve geliştirme çalışmalarına ağırlık vermiştir. Bu çalışmada, dünyada ve Türkiye’de yenilenebilir enerji kaynaklarının kullanım durumları ve kurulum maliyetleri güncel verilerle incelenmiştir. Çalışma neticesinde yenilenemez enerji kaynağı olan kömürün küresel çapta %36’lık payla günümüzde hala en çok tüketilen enerji kaynağı olduğu tespit edilmiştir. Buna karşın toplam temiz enerjinin elektrik üretimindeki payının %38 seviyelerine geldiği belirlenmiştir. Bu bağlamda yenilenebilir enerji kullanımının dünyada ve Türkiye’de hızlı bir şekilde yaygınlaşması, yenilenemez enerjiye olan talebin hızla azaltılması hem çevresel hem de kaynak çeşitliliği açısından oldukça önem arz etmektedir.
