Abstract

Hydrogen pumps using high-temperature proton conductors have been examined as a candidate means of hydrogen separation from syngas. Durability to CO ₂ is a main concern for the alkali-earth-containing perovskites and was tested for a few typical compositions. Ce-excluded and cerate-zirconate solid solution electrolytes, SrZr_0.9Y_0.1O _3-α, and BaCe_0.6Zr_0.3Nd _0.1O_3-α were stable in CO₂-containing atmospheres, whereas they showed poor overpotential characteristics when platinum electrodes were used. It is demonstrated that the hydrogen pumping properties can be much improved for the case of SrZr_0.9Y _0.1O_3-α by the use of palladium anode and SrCe _0.95Yb_0.05O_3-α interlayer for the cathode.
