文摘
- •
Porous stainless steel supports for composite porous membranes are investigated.
- •
Hydrogen transport is dominated by Knudsen diffusion and Poiseuille flow.
- •
Substrates’ geometrical factors significantly influence the overall hydrogen flux.
- •
Tungsten impregnation can significantly reduce the pore size with only a limited effect on the hydrogen flux.
