Synthesis and characterization of thermally stable palladium-based composite membranes for high temperature applications
… in electroless-plated palladium-based composite membranes has been revisited. Palladium was doped with a higher melting point element such as ruthenium or platinum and the rate of increase of the nitrogen leak in the temperature range of 500-600 ºC was determined. The results showed that doping …

Reaction Condition Dependence of Different Overpotential Components in Electrochemical Hydrogen Catalysis
… in hydrogen evolution catalysis. We employ a Pd membrane double cell to spatially isolate charge transfer and chemical reaction steps in HER catalysis, deconvoluting their overpotential contribution under different reaction conditions. We analyze how pH, and the introduction of poisons and …

Catalysts and materials development for fuel cell power generation
… for both low-temperature polymer electrolyte membrane (PEM) fuel cell as well as high-temperature solid oxide fuel cell (SOFC) applications. Novel catalysts were developed to generate hydrogen for PEM applications from the oxidative steam reforming of methanol. The activity of lanthanum nickel …

Fabrication of Ultrathin Palladium Composite Membranes by a New Technique and Their Application in the Ethanol Steam Reforming for H₂ Production
… a new technique for the preparation of ultrathin Pd based membranes supported on a hollow-fiber α-alumina substrate for H₂ separation. The effectiveness of the membranes is demonstrated in the ethanol steam reforming (EtOH SR) reaction in a membrane reactor (MR) for H₂ production. The membrane …

Design and Modeling of Nanostructured Palladium-Based Hydrogen-Selective Membranes
… helium, a major byproduct of fusion reactions. Pd-based membranes, recognized for high permeance and selectivity, offer a promising solution for this separation with minimal energy, cost, and footprint. However, these membranes have not yet been tailored for nuclear fusion applications. There …
