A project started 10 years ago by researchers at Washington State University has produced a solid-oxide fuel cell that can convert jet fuel or gasoline to electricity and deliver electrical power on commercial airplanes.
The electrochemical reaction caused when using a solid-oxide fuel cell to convert fuel to electricity is approximately four times more efficient than a combustion engine. These fuel cells increase fuel efficiency also reduce emissions of harmful pollutants. The team imagines using these fuel cells with a battery to power auxiliary power units, instead of using gas turbines to run lights, navigation systems and other electrical systems.
