Intermediate Temperature Fuel Cells

Fabrication and Characterization of Materials and Components for Fuel Cells Working at Intermediate Temperatures

The worldwide development of fuel cells and electrolysers has so far almost exclusively addressed either the low temperature window (20 – 200 °C) or the high temperature window (600 – 1000 °C). This work concerns the development of key materials and components for a new generation of fuel cells and electrolysers operational in the intermediate temperature range: from 200 to 400 °C. The intermediate temperature interval is of importance for the use of renewable fuels. Furthermore, electrode kinetics are significantly enhanced and thus non-noble metal catalysts might be used.

Scant information concerning  fuel cell  tests within this temperature range has been reported. This is mainly due to limitations regarding the density of the electrolyte layer, which originates from the necessity to sinter the materials at low temperatures (often below 400 °C), and partly due to decomposition during operation.
