PEM (Proton Değiştirici Membran) yakıt pilleri;
düşük çalışma sıcaklıkları, yüksek güç yoğunlukları ve yüksek enerji dönüşüm
verimlerinden dolayı otomobiller ve sabit uygulamalar için potansiyel bir güç
kaynağı olarak oldukça dikkat çekmektedir. PEM yakıt pilinin verimliliğinin
arttırılması ve iyileştirilmesi adına matematiksel modelleri oluşturularak
sayısal veriler yardımıyla daha uygun yakıt pili tasarımları yapılabilmektedir.
Bu çalışmada, prototip araç için tasarlanacak PEM
yakıt pili sistemi, MATLAB Simulink programı yardımıyla modellenmiş, benzetimi
yapılmış ve sonuçları sunulmuştur. Yakıt pili sistem modeli; membran içi akış
modelleri, gerilim üretimi ve kayıplarının modellenmesi ile yapılmıştır. Analiz
edilen parametreler iki ve üç boyutlu grafikler halinde sunularak sonuçların tartışılmasına
olanak sağlanmıştır.
PEM (Proton Exchange Membrane) fuel cells; due
to its low operating temperatures, high power densities and high energy
conversion efficiencies, it attracts considerable attention as a potential
power source for automobiles and stationary applications. In order to improve
and improve the efficiency of the PEM fuel cell, mathematical models can be
created and more suitable fuel cell designs can be made with the help of
numerical data. In this study, the PEM fuel system which will design for
prototype vehicle is modeled with the help of the MATLAB Simulink program,
simulated and presented. Fuel system model includes membrane flow models,
voltage generation and loss modeling. The values of the important parameters
were calculated, and two and three dimensional graphics were prepared to allow
the results to be appreciated.
