Abstract:
A high-performance Pd membrane for H2 separation was prepared by the modified electroless plating method.In order to obtain pure H2 for fuel cell use,the NH3 cracker was integrated with a Pd membrane-based purifier and the permeation performance of Pd membrane (H2 flux, recovery yield and purity)was investigated at 510℃ and a pressure range from 0.1 MPa to 0.5 MPa.High separation efficiency was achieved with such an intergrated system.A 75 cm3·cm-2·min-1H2 flow with purity as high as 99.93% could be obtained.Throughout a 120 h stability test, the H2 flux and recovery yield were maintained at 63 cm3·cm-2·min-1and 85% respectively.
