Abstract

Bu çalışmada Polimer Elektrolit Membran (PEM) yakıt pilinde kullanılan yakıtların sıcaklık değerleri belirlenmiş ve bu yakıtlar için optimum sıcaklık aralıkları elde edilmiştir. Anot ve katot kısımlarında saf hidrojen ve oksijen kullanılmıştır. Bu çalışmada nem miktarı %40, hidrojen miktarı 0.3 ml/dk ve oksijen miktarı 0.5 ml/dk olarak alınmıştır. Sistemdeki hat sıcaklık değerleri de 5°C fark ile 40-80°C arasında test edilmiştir. 40°C'de yapılan deneylerde volt değeri 0.442V ve akım değeri 1.81A alındığında sistemde elde edilen güç değeri 0.804W olarak bulunmuştur. Deneyde 75°C'de akım değeri 1.8A ve volt değeri 0.535V iken sistemdeki güç değeri 1.025W olarak bulunmuştur. En düşük W değeri 40°C'de 0.804W, en yüksek W değeri 75°C'de 1.025W olarak hesaplanmıştır. Bu hesaplamalar tablolar ve grafikler halinde sunulmuştur.

Performance Analysis of Temperature Changes of Fuels Used in Pem Fuel Cell

Abstract

In this study, the temperature values of the fuels used in Polymer Electrolyte Membrane (PEM) fuel cell were determined and the optimum temperature ranges were obtained for these fuels. Pure hydrogen and oxygen were used in the anode and cathode portions. In this study, moisture was taken as 40%, hydrogen amount as 0.3 ml/min and oxygen amount as 0.5 ml / min. Line temperature values in the system were also tested between 40-80°C with a 5°C difference. In the experiments carried out at 40°C, when the volt value was taken as 0.442V and the current value was taken as 1.81A, the power value obtained in the system was found to be 0.804W. In the experiment, when the current value is 1.8A and the volt value is 0.535V at 75°C, the power value in the system is found to be 1.025W. The lowest W value was calculated as 0.804W at 40°C and the highest W value was calculated as 1.025W at 75°C. These calculations are presented in tables and graphs.
