This paper review the principle of hydrogen permeation, type of alloys and the fabrication methods. At last, the progress and achievements on palladium alloy membranes by Northwest Institute for Non-Ferrous Metal Research are emphasized.展开更多

Due to excellent comprehensive properties palladium composite membrane will become the future direction of development. At the same time it will develop preparation methods of the membrane support body with high mechanical strength and heat resistance and low-cost and palladium-based membrane. Also it will explore high service life and high transmittance of novel composite membrane.展开更多

There is experimentally shown that penetration of hydrogen in palladium is accompanied with strong and micro structural effects, as well as grain shifts, etc. Moreover, the hydrogen saturation of palladium causes form-changing (bending) of palladium plate. These effects, undoubtedly, must be taken in account in technologies of low-temperature diffusion membrane apparatus exploitation.展开更多
