An eco-system using hydrogen as a fuel is being proposed as a solution to respond to global climate change. The Fuel cell is one of the essential parts of utilizing hydrogen energy fulfilling energy cycles without CO2 generation. A solid oxide fuel cell (SOFC), a fuel cell in which the electrolyte is a solid oxide, has the advantage of having the highest efficiency among fuel cells.

However, there are disadvantages of general SOFCs that come from the fact that the operating temperature is high. Since it operates at high temperatures, it has several disadvantages such as low long-term stability, and the high cost of materials. The SOFC fabrication approach using thin-films can achieve high performance and stability even at low operating temperatures. We especially focus on improving the performance of thin-film SOFC and optimizing the thin-film components suitable for large-area/commercial processes.   

Investigating the thin films, we explore optimized conditions to promote the commercialization of thin-film SOFC.
