Electrolyser Technology Advancement: Solid Oxide Electrolysis Using GDC as Electrolyte

Abstract
This study centres on the simulation of Solid Oxide Electrolyser Cells (SOEC) for hydrogen production using Gadolinium-Doped Ceria (GDC) as the electrolyte. The SOEC model was created and its electrochemical performance, hydrogen output, and system efficiency at high temperatures were simulated in COMSOL Multiphysics and Aspen Plus. Simulation results for GDC were benchmarked against Yttria-Stabilized Zirconia (YSZ) literature. GDC showed better ionic conductivity at lower operating temperature, thus improving efficiency, reducing energy consumption, and increasing hydrogen production compared to conventional systems that utilized YSZ. This research illustrates the benefits of utilizing GDC as an electrolyte material towards lower cost and higher efficiency sustainable hydrogen production while showcasing the use of multi-software simulations for the design of advanced electrochemical systems.
