Special Issue Information

Dear Colleagues,

In the current conjuncture of clean energy sources diversification, energy security issues and the current political drive to reduce carbon emissions, fuel cell energy systems are critical in a distributed energy development structure and offer a credible and flexible solution for economic and environmental sustainability. Cost-effective electro-catalysts with high sorption reactivity and stability are currently the most demanded subject for innovative research and the main technological obstacle for fuel cell power sources to becoming an attractive and competitive alternative.

The aim of this Special Issue is to look at recent progress and trends in fuel cell research with respect to the design and synthesis of enhanced catalyst materials, structure-property, and nano-porous high surface area substrate to increase transport/kinetics properties, energy conversion performance, and durability of fuel cells. Areas of interest range from fundamental research and advanced in-situ catalyst characterization studies to the development of new nanostructured redox catalysts and growth formulations and computer modelling.

The present work involves the development of a novel method for the fabrication of zirconium nickel (Zr(x)Ni(y)) alloy used as a nanocatalyst to improve the hydrogen storage properties of the Mg/MgH2 system. The catalyst was fabricated through the high-pressure reactor and activated under hydrogen prior to being mechanically milled with the MgH2 for 5 h under argon. The microstructure characterisation of the samples was determined via SEM-EDX (scanning electron microscope analysis–energy dispersive X-ray spectroscopy), XRD (X-ray diffraction) and FE-HRTEM (field emission high resolution transmission electron microscopy), and the desorption characteristic of the nanocomposite (10 wt.% Zr(x)Ni(y)–MgH2) was determined via TPD (temperature-programmed desorption). The nanostructured MgH2 powder milled with 10 wt.% of the activated Zr(x)Ni(y) based nanocatalyst resulted in a faster hydrogen release—5.9 H2-wt.% at onset temperature 210 °C/peak temperature 232 °C. The observed significant improvement in the hydrogen desorption properties was likely to be the result of the impact of the highly dispersed catalyst on the surface of the Mg/MgH2 system, the reduction in particle size during the ball milling process and/or the formation of Mg0.996Zr0.004 phase during the milling process.
