Solid Oxide Fuel Cell

A fuel cell that employs a solid, ionically conductive material as electrolyte. Typically zirconium oxide (ZrO2) treated with Y2O3, and O-2 is transported from the cathode to the anode. Any CO in the reformate gas is oxidized to CO2 at the anode.

There are many different geometries of solid oxide fuel cells:

They function at the highest temperature of the different types of fuel cell (about 900°C to 1000°C) and can reform most fuels internally.
