N2 - A solid oxide fuel cell (SOFC) is a clean and highly efficient power generation device, garnering great interest in the context of carbon neutralization. In addition to pure hydrogen, it is also applicable to various hydrocarbon fuels for power generation, including gas hydrate (GH)─a promising energy resource that is reserved globally. Here, for the first time, we demonstrate the utilization of CH4-CO2-rich fuel gas released from lab-made GH in SOFC to achieve the purpose of gas and power cogeneration through the so-called GH-SOFC. The experiment was performed using the classic cermet Ni-based, anode-supported cells to evaluate the electrochemical performance and carbon deposition of GH-SOFC (837 mW cm-2 @800 °C), which is found to be higher than the CH4-CO2-SOFC with the stoichiometric ratio for the dry reforming reaction. Furthermore, we achieved high methane conversion rates with GH-SOFC, surpassing CH4-SOFC and CH4-CO2-SOFC. After the durability test, we observed nearly no carbon deposition on the anode, indicating a robust performance of the good applicability of SOFC for efficient utilization of GH.
