AB  - Hafnium-based interriletallics Hf(2)Fe, Hf(2)Co and Hf(2)Ni are investigated as hydrogen absorbers at atmospheric pressure and their electrocatalytic activities are compared. The absorption process is carried out in typical volumetric apparatus. Their crystal structures and morphological characteristics are investigated by X-ray difractometry (XRD) and scanning electron microscopy (SEM). According to the absorption abilities, the investigated intermetallics can be ordered as follows: Hf(2)Fe GT Hf(2)Co GT Hf(2)Ni. Ab initio calculations, within the framework of the density functional theory (DIFT), as implemented in the full-potential (linearized) augmented plane-wave (FP/LAPW) method, confirms the experimental investigations. The calculations are important as a way of predicting the best cathode and storage materials. (C) 2009 Elsevier B.V. All rights reserved.

AB  - Faraday efficiencies and energy consumptions of a small commercial proton exchange membrane (PEM) and an alkaline electrolyzer designed at our laboratory and equipped with different cathode materials were determined. Our experimental data indicate that the alkaline electrolyzer has a higher Faraday efficiency than the PEM electrolyzer, but, on the other hand, less energy is required for the PEM electrolyzer compared with the alkaline one. The results are discussed with regard to the special advantages of electrolyzers of both types.

AB  - The intermetallic phases along the Pt-Mo phase diagram, singly or in combination with specific ionic activators, have been investigated as cathode materials for the production of hydrogen by electrolysis from water KOH solutions in an attempt to decrease energy consumption. The influence of ionic activators (activating compounds) on energy consumption was significant. The intermetallic phases, as cathode materials, were activated by the surface deposition of activating compounds from electrolyte. The influence of these cathode materials on the electrolytic evolution of hydrogen was discussed in the context of transition metals features and their electronic configuration.
