Abstract
A mixed protonic-electronic conductor made of La5.5W0.45Nb0.15Mo0.4O11.25âδ (LWNM) has been developed by partial co-substitution of W with Nb and Mo in La5.5WO11.25âδ aiming to improve the hydrogen permeation property. A hydrogen permeation flux of 0.195 mL/minâ
cm2 was obtained at 1000 °C with a mixture of 50% H2-50% He as the feed gas under dry condition. More importantly, there was no obvious decline of the hydrogen flux during 80 h operation even with CO2 in the feed gas.
