The water–gas shift (WGS) reaction is used to shift the CO/H₂ ratio prior to Fischer–Tropsch synthesis and/or to increase H₂ yield. A WGS membrane reactor was developed using a mixed protonic–electronic conducting SrCe_0.9Eu_0.1O_3−δ membrane coated on a Ni–SrCeO_3−δ support. The membrane reactor overcomes the thermodynamic equilibrium limitations. A 46 % increase in CO conversion and total H₂ yield was achieved at 900 °C under 3 % CO and 6 % H₂O, resulting in a 92 % single pass H₂ production yield and 32 % single pass yield of pure permeated H₂.
