Low temperature solid oxide fuel cells (SOFCs) that are highly scalable and cost effective

A series of new Harvard technologies enables operation of SOFCs at low temperatures (300 deg. C to 600 deg. C). Operation at these temperatures (vs. the current ~1000 deg. C) is a sought-after goal of the fuel cell industry – because it will significantly expand practical applications for SOFCs. The Harvard SOFCs are made using novel nano-fabrication techniques based on well-proven semiconductor processes. These micro-scale fuel cell devices also enable applications where a small form-factor is critical (such as portable electronics), yet the devices are easily scalable to provide a wide range of power outputs. A related Harvard innovation, the "accelerated oxygen exchange" process, can significantly improve performance of any SOFC.


Applications for this technology are in the fuel cell, solid oxide fuel cell, and energy industries.
