INVESTIGATION OF PERFORMANCE PARAMETERS, ENERGY AND EXERGY ANALYSIS OF MOLTEN CARBONATE FUEL CELL (DIR-MCFC) WORKING WITH INTERNAL REFORMER

Abstract

Direct Internal Reformed Molten Carbonate Fuel Cells (DIR-MCFC) stand out in the energy sector by offering a solution for a wide range of applications. This technology offers a wide potential in different industrial fields with its high energy efficiency, ability to utilize various fuels and stable operation at high temperatures. A detailed understanding of the factors affecting the thermodynamic performance of DIR-MCFCs is vital for effective optimization of this technology. In this context, extensive modeling and simulation of the DIR-MCFC system has been extensively studied to understand and improve the impact of critical parameters such as current density, fuel utilization rate, cell temperature and CO2 utilization rate on the system performance. In the analysis of the DIR-MCFC, the maximum power values obtained at 600°C, 625°C and 650°C cell temperatures were measured as 18454.26338 kW, 21869.68782 kW and 24847.2680 kW, respectively. This study showed that increasing the cell temperature at constant current density increases the energy and exergy efficiency, with the highest performance achieved at 625°C (50.15% energy efficiency, 44.91% exergy efficiency). At maximum fuel utilization rate (96%), the power was 23512,730 kW with energy and exergy efficiencies of 34.569% and 30.958%, respectively.

Öz

Doğrudan İç Reformlu Erimiş Karbonat Yakıt Pilleri (DIR-MCFC), enerji sektöründe oldukça çeşitli uygulamalara yönelik bir çözüm sunarak dikkat çekmektedir. Bu teknoloji, yüksek enerji verimliliği, çeşitli yakıtları kullanma yeteneği ve yüksek sıcaklıklarda kararlı çalışabilme kapasitesi gibi özellikleri ile farklı endüstri alanlarında geniş bir potansiyel sağlamaktadır. DIR-MCFC'lerin termodinamik performansını etkileyen faktörlerin ayrıntılı bir şekilde anlaşılması, bu teknolojinin etkili bir şekilde optimize edilmesi için hayati öneme sahiptir. Bu bağlamda, DIR-MCFC sisteminin kapsamlı modellemesi ve simülasyonu akım yoğunluğu, yakıt kullanım oranı, hücre sıcaklığı ve CO_2 kullanım oranı gibi kritik parametrelerin sistem performansına etkisini anlamak ve geliştirmek için kapsamlı bir çalışma yapılmaktadır. DIR-MCFC'nin analizinde 600°C, 625°C ve 650°C hücre sıcaklıklarında elde ettiği maksimum güç değerleri sırasıyla 18454,26338 kW, 21869,68782 kW ve 24847,2680 kW olarak ölçüldü. Bu çalışma, sabit akım yoğunluğunda hücre sıcaklığındaki artışın enerji ve ekserji verimini artırdığını, en yüksek performansın 625°C'de (%50,15 enerji verimi, %44,91 ekserji verimi) elde edildiğini gösterdi. Maksimum yakıt kullanım oranında (%96) gücü 23512,730 kW olarak enerji ve ekserji verimleri sırasıyla %34,569 ve %30,958 olarak ölçüldü.
