Abstract

Bu çalışmada, düşük sıcaklıklarda çalışan tek kanallı bir proton değişim membranlı yakıt hücresi modellenmiştir. Hazırlanan model deneysel verilerle karşılaştırılmış ve doğruluğu kanıtlanmıştır. Bu model kullanılarak, kanal yüksekliği sabitken kanal genişliğindeki değişimin hücre performansına etkisi ve kanal kesit alanı sabitken kanal geometrisindeki değişim araştırılmıştır. Reaktantın difüzyon tabakası ile temas ettiği alanın büyütülmesinin performans artışı sağladığı tespit edilmiştir. Ancak düşük voltajlarda çalışırken taban açısı ve kanal genişliğinin artmasıyla artan konsantrasyon kayıplarının azaldığı gözlemlenmiştir.

Investigation of the cross-section area geometry effect on the performance of PEM fuel cell

Abstract

In this study, a proton exchange membrane fuel cell operating at low temperatures with a single channel is modeled. The prepared model has been compared with experimental data and its accuracy has been proved. Using this model, the impact of the change of the channel width on the cell performance with the channel height being constant and the change of the channel geometry with the channel cross-sectional area being constant was investigated. It has been found that the enlargement of the area where the reactant contacts the diffusion layer provides an increase in performance. However, when working at low voltages, it has been observed that increasing concentration losses decrease with increasing base angle and channel width.
