In the context of global efforts to reduce greenhouse gas emissions and combat extreme warming, direct dry reforming methane reaction in solid oxide fuel cells presents a promising avenue for clean energy production. This study delves into influence temperature, composition, current density on kinetics cells. Power Law Langmuir-Hinshelwood kinetic models were proposed highlight impact operating conditions reactions. Results revealed that feed composition strongly affects conversion, with higher contents resulting lower conversions. Increasing CH4/CO2 ratio increases rates, effect decreases at 1.25. The changes concentration rate are more significant than those carbon dioxide. However, increasing dioxide enhances conversion. exothermic nature CO2 adsorption suggests process is thermodynamically favourable reforming, elevated temperatures generally improve rates conversion by removing deposits providing needed break down chemical bonds which facilitating its transformation. A significantly equilibrium constant further highlighting positive role electrochemical reactions reforming. aims fill knowledge gap regarding behaviours cells, offering critical insights advancing anode design, thus contributing development cell technologies address warming emissions.
