Hydrogen transport properties of palladium film prepared by colloidal spray deposition

▸ Developed colloidal spray deposition to fabricate Pd films on porous supports. ▸ Dense Pd films with thickness ≤11 μm on YSZ substrates having pore size of 3-7 μm. ▸ H2 permeation limited by both the bulk and gas-phase transport through the support.
