Abstract:

 In this study, the performance of an anode supported planar single-chamber solid oxide fuel cell prepared by single-step co-sintering method is tested. Additionally, the effects of reduced electrolyte thickness and increased anode thickness proven beneficial in achieving low curvature during sintering on cell performance were investigated. All cells are composed of gadolinium-doped cerium-lanthanum strontium cobaltite ferrite CGO-LSCF, gadolinium-doped cerium CGO and nickel oxide-gadolinium-doped cerium NiO-CGO as cathode, electrolyte and anode. Each cell is made of porous multi-layer structures with different thickness and thickness ratios. The performances of these cells were tested in methane-oxygen mixtures in a single chamber at 600C. The maximum power density and open circuit voltage of the final planar cell with a thickness of 800:20:40 µm, anode: electrolyte: cathode, were obtained as 30.69 mW cm-2 and 0.71 V respectively, in an environment with a methane-oxygen ratio R of 1.

 Bu çalışmada, tek aşamalı ortak sinterleme yöntemiyle yapılan anot destekli, düzlemsel tek odacıklı katı oksit yakıt pilinin performansı test edilmiştir. Ek olarak, azaltılmış elektrolit kalınlığının ve arttırılan anot kalınlığının sinterleme sırasında düşük eğrilik elde edilmesinde faydalı olduğu kanıtlandığından dolayı pil performansı üzerindeki etkileri araştırılmıştır. Tüm piller katot, elektrolit ve anot olarak: gadolinyum katkılı seryum-lantan stronsiyum kobaltit ferrit CGO-LSCF, gadolinyum katkılı seryum CGO ve nikel oksit- gadolinyum katkılı seryumdan NiO-CGO oluşmuştur. Her bir pil farklı kalınlıkta ve farklı kalınlık oranlarında gözenekli ve çok katmanlı yapılar halinde yapılmıştır. Bu pillerin performansları 600C sıcaklıkta tek haznede metan-oksijen karışımlarında test edilmiştir. Bu çalışma kapsamında anot kalınlığı 800 µm, elektrolit kalınlığı 20 µm ve katot kalınlığı 40 µm olan nihai düzlemsel pilin maksimum güç yoğunluğu ve açık devre voltajı, metan-oksijen oranı Rnın 1 olduğu ortamda sırasıyla 30.69 mW cm-2 ve 0.71 V olarak elde edilmiştir.
