Palladium-copper membranes for hydrogen separation

This communication summarizes key elements and facts of PdCu alloy membranes for H2 separation by reviewing fundamentals and literature reports, such as the PdCu phase diagram and its implications toward membrane permeability and stability, the phase and composition segregation behavior, and the intricate phase structure-composition-stability-permeability relationship. The inconvenient challenges for applying PdCu alloy membranes due to its...
