Modeling Study of Solid Oxide Fuel Cell Operating on Reformed NATO F-76 Diesel Fuel

Abstract

Fuel cells provide great potential for electric power generation on-board ships. Ships use marine diesel fuel for marine main and auxiliary engines . In this work, this paper presents the performance analysis of a planar solidoxide fuel cell (SOFC) under reformed diesel fuel. A detailed solid-oxide fuel cell model is used to study the influences of various operating parameters on cell performance. Significant differences in efficiency and power density are observed for isothermal operational regimes. In the model, electrochemical kinetics, gas dynamics and species are coupled. The model predicts polarization curve, velocity and species concentration and current distribution in the cell depending on fuel cell temperature and electrodes/ electrolyte materials used in the components YAKIT DÖNÜŞTÜRÜCÜDE DÖNÜŞTÜRÜLMÜŞ DİZEL YAKIT İLE ÇALIŞAN KATI OKSİTLİ YAKIT PİLİNİN MODELLEME ÇALIŞMASI Özetçe Yakıt pilleri, gemilerde elektrik gücü üretimi için büyük bir potansiyel sağlamaktadır. Gemiler, ana ve yardımcı makinaları için deniz tipi dizel yakıt kullanmaktadır. Bu çalışmada, yakıt dönüştürücüde dönüştürülmüş dizel yakıtı ile çalışan düzlemsel tip katı oksitli yakıt pilinin performans analizi sunulnuştur. Detaylı bir katı oksitli yakıt pili modeli, çeşitli işletme parametrelerinin hücre performansı üzerindeki etkilerini çalışmak için kullanılmıştır. İzotermal çalışma rejimleri için verim ve güç yoğunluğunda önemli farklar gözlemlenmiştir. Modelde elektrokimyasal kinetikler, gaz dinamiği ve maddeler birleştirilmiştir. Model, yakıt pili sıcaklığına ve bileşenlerde kullanılan elektrod/elektrolit malzemelerine bağlı olarak polarizasyon eğrisini, hızı, madde konsantrasyonlarını ve akım dağılımını tahmin etmektedir
