Abstract

Hydrogen release behavior from mixed-perovskite oxide, yttrium and cobalt doped barium-zirconate, BaZr_0.955Y_0.03Co_0.015O_3-a (BZYC) exposed to D₂ or D₂O atmosphere was studied by thermal desorption spectroscopy (TDS) detecting deuterium gas (D₂) and heavy water vapor (D₂O) separately. The release of hydrogen appeared at around 1000 K. Hydrogen solubility was higher in the BZYC sample exposed to the D₂O.
