Solid oxide fuel cell (SOFC) is a device that produces electricity directly from oxidizing a fuel. Some of the advantages are operating at high temperatures and converting various hydrocarbon fuels directly into electricity. This study investigates the parameters that influence the cell characteristics of a cathode-supported SOFC (CSSOFC) model. Numerical modeling has been performed utilizing low calorific value coal gases, generator gas, and water gas by deriving an SOFC model based on finite element method (FEM). The effects of fuel compositions, temperature, pressure, and porosity on the performance of the developed SOFC have been examined using COMSOL software. These effects are presented by polarization and power curves. A mathematical model has been developed to determine the performance of a CSSOFC with low calorific value coal gases that were obtained from Turkey/Turk coal. It is predicted that the performance of CSSOFC is higher than that of the electrolyte-supported SOFC (ES-SOFC) for all studied fuels. Besides this, the cost of the cathode supporting materials for high-performance CSSOFC is low. The performance of SOFC using water gas is higher than that of the generator gas. This being maybe the hydrogen content of the water gas is higher compared with the generator gas. Therefore, the result confirmed that low calorific value coal gases could be used in SOFCs as a source of fuel. Moreover, the power of the CSSOFC increases as the pressure, temperature, and hydrogen content increase.

固体氧化物燃料电池（SOFC）是直接通过氧化燃料产生电能的设备。一些优点是在高温下运行，并将各种碳氢化合物燃料直接转化为电能。这项研究调查了影响阴极支持的SOFC（CS SOFC）模型的电池特性的参数。通过基于有限元方法（FEM）推导SOFC模型，利用低热值煤气，发电机煤气和水煤气进行了数值建模。使用COMSOL软件检查了燃料成分，温度，压力和孔隙度对已开发SOFC性能的影响。这些影响由极化和功率曲线表示。已经开发出数学模型来确定CS的性能从土耳其/土耳其煤获得的具有低热值煤气的SOFC。可以预见，对于所有研究的燃料，CS SOFC的性能都高于电解质支持的SOFC（ES-SOFC）。除此之外，用于高性能CS SOFC的阴极支撑材料的成本低。使用水煤气的SOFC的性能要比发电煤气的性能高。这可能是因为水煤气中的氢含量比发电机煤气中的更高。因此，该结果证实了低热值煤气可用于SOFC中作为燃料来源。而且，CS SOFC的功率随压力，温度和氢含量的增加而增加。
