The electrochemical hydrogen pumping using Ba doped LaYbO₃ oxide (La_0.9Ba_0.1YbO_3-α, LBYb-91) was investigated in this work. It was found that LBYb-91 can conduct a large amount of protons as much as 100 mA cm^-2 and the theoretical hydrogen evolution is actually occurred by the proton conduction. It was also found that LBYb-91 has high chemical stability against CO₂ and H₂O, and showed a comparable cell performance to SrZr_0.9Y _0.1O_3-α (SZY-91) with porous palladium electrode. The present study demonstrated that LBYb-91 is a potential candidate electrolyte material for the electrochemical cell to separate hydrogen from the reformed natural gas.
