The fuel cell is an electrochemical device that provides a sustainable, clean source of energy. In particular, the solid oxide fuel cell (SOFC) is known as a fuel cell with high energy efficiency. A novel approach is used to fabricate the porous cathode of SOFC using an extruder and 3D printing. The 3D printer is considered because it offers a more cost-effective approach, has a high accuracy control, and it is a one step process to print cathodes. First, a roller is used to mix ceramic and polymer powders uniformly. An extruder will then be used to make filament for the 3D printer with the mixed ceramic and polymer powder. The print-outs of the cathode will be made with the filament using the 3D printer. They will then be sintered in a furnace to obtain the porous ceramic cathode used for SOFCs. A sintered cathode has been combined with other parts to make the SOFC. A fuel cell tester has been used to obt in characterization of SOFC in terms of current density and power density. The ceramics used in the research are LSM/YSZ, and the thermoplastics under investigation is Nylon 12. Other cathode materials such as LSCM will be explored in the future.

Role: I was in charge of redesigning the circuitry of our extruder, that was malfunctioning. I also was tasked to taking time to complete the extrusion process.
