The catalytic and electrocatalytic decomposition of NH3 was studied at 350-650 degrees 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. (c) 2006 Elsevier B.V. All rights reserved.
