Abstract

A new method for hydrogen separation to acquire high-purity hydrogen using an oxygen-permeable ceramic membrane is proposed and verified in this work. A high hydrogen separation rate of up to 16.3 mL cm−2 min−1 was achieved on an asymmetric dual-phase membrane at 900 °C. No performance degradation was observed in a long-term operation with the feed gas containing 200 ppm H2S.
