Stoukides Keywords: Strontia-ceria-ytterbia; Ammonia decomposition; Proton conductor; Ruthenium catalyst Abstract: The catalytic and electrocatalytic decomposition of NH.sub.3 was studied at 350-650 [degrees]C and atmospheric total pressure, using a single-chamber H.sup.+ conducting cell-reactor. The H.sup.+ conductor was a strontia-ceria-ytterbia (SCY) perovskite of the form: SrCe.sub.0.95Yb.sub.0.05O.sub.3-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.
