Abstract

This study investigates a compact palladium membrane module (CPMM) for hydrogen purification, assembled by diffusion bonding at a low-temperature (450^◦ C). This CPMM resulted in hydrogen (H₂) flux of 18.3 mL cm⁻² min⁻¹ with H₂ /N₂ selectivity of over 1100. The H₂ purification test using a 60% H₂ /40% CO₂ mixed gas confirmed that the CPMM can separate H₂ with a concentration of more than 99%, with a pressure difference of 5 bar. Moreover, the volume of the diffusion bonded membrane module is decreased by 81.4% than the flame-type membrane module pre-studied in our laboratory.
