Solid oxide fuel cells (SOFCs) are efficient and clean power-generating devices. Unlike traditional generators, which involve multiple energy conversion steps, SOFCs produce electricity through a unique process. SOFCs also save about 30 percent of energy compared to gas turbines of the same scale at the same power output. What makes SOFCs so efficient? And as a form of clean energy, how do SOFCs differ from wind and solar power? Explore this new generation of clean energy.
