NH3 decomposition in a single-chamber proton conducting cell

The catalytic and electrocatalytic decomposition of NH3 was studied at 350–650 °C and atmospheric total pressure, using a single-chamber H+ conducting cell-reactor. The H+ conductor was a strontia–ceria–ytterbia (SCY) perovskite of the form: SrCe0.95Yb0.05O3−a. A Ru film was used as catalyst-electrode. The effects of imposed currents, temperature and inlet gas composition on the reaction rate were examined.
