A zero-dimensional model of a 2nd generation planar SOFC using calibrated parameters

Bu makalede güç sistemlerinin benzetimi için geliştirilen ikinci jenerasyon düzlemsel eş akımlı SOFC'nin (katı oksitli yakıt pili) sıfır boyutlu matematiksel modeli verilmektedir. Model hidrojenin elektrokimyasal oksitlenmesini ve ayni zamanda metanın reformasyon reaksiyonu ile su-gaz kayma reaksiyonunu da hesaba katar. Makalenin önemli bir kısmı elektrokimyasal alt - model olup özgül parametrelerin kalibrasyonu için deneysel veriler kullanılmıştır. SOFC modeli, enerji sistem benzetimi için tasarımlanmış DNA benzetim programı içinde yürütülmüştür. Sonucu, birçok farklı SOFC'li güç sistemlerinin benzetimi için uygun olan doğru ve esnek bir araçtır.

Kalibre edilmiş parametreler kullanılarak ikinci jenerasyon düzlemsel SOFC' nin bir sıfır boyutlu modeli

This paper presents a zero-dimensional mathematical model of a planar 2nd generation co-flow SOFC developed for simulation of power systems. The model accounts for the electrochemical oxidation of hydrogen as well as the methane reforming reaction and the water-gas shift reaction. An important part of the paper is the electrochemical sub-model, where experimental data was used to calibrate specific parameters. The SOFC model was implemented in the DNA simulation software which is designed for energy system simulation. The result is an accurate and flexible tool suitable for simulation of many different SOFC-based power systems.
