Facing the emission-cutting trend, clean and high efficient energy sources are being earnestly pursued worldwide. Solid oxide fuel cell (SOFC) is a novel power generating technology with high electric conversion efficiency and adoption of versatile carbon-based fuels. From 2003, INER launched the SOFC project. The R&D is aiming to help cutting emission, balancing electricity bill, and providing stable power supply. With the fostering domestic manufacturing and excellent design capabilities, INER is facilitating the process of lowering manufacture cost further and is improving the performance continuously.
