Materials scientists at the Harvard School of Engineering and Applied Sciences (SEAS) and SiEnergy Systems LLC have demonstrated the first macro-scale thin-film solid-oxide fuel cell (SOFC). While SOFCs have previously worked at the micro-scale, this is the first time any research group has overcome the structural challenges of scaling the technology up to a practical size with a proportionally higher power output. Reported online April 3 in Nature Nanotechnology, the demonstration of this fully functional SOFC indicates the potential of electrochemical fuel cells to be a viable source of clean energy.
