The worldwide conventional thermal engines used for power generation needs biofuels to meet nowadays environmental requirements. Such technologies are characterized by their very limited energy conversion efficiencies, which, especially when short size electrical devices are employed, are not higher than 20%. As a consequence, the electrochemical devices, such as the solid oxide fuel cell…
The nowadays world fast technological development has raised the demand of electrical/mechanical energies to levels well above the capacity of their generation exclusively from sustainable/renewable sources. This implies that significant fractions of usable energies have to be derived from fossil fuels, whose consequence has strong negative impacts over the environment, one of them relate…
An efficient and low-cost device for hydrogen production should mitigate the use of fossil fuels and enhance bioresources in producing this energy vector. Cost and size-dependent performance of commercial electrolysers are the current limits of these technologies for the storage of renewable energy produced locally. By studying novel materials with limited or no content of critical raw ma…
This proposal concerns with the development of novel non-noble metal catalysts for solid oxide electrochemical cells. The materials suggested are based on cermets (Ni-alloys combined with doped ceria) or Ni-doped perovskites (Co or Fe based), which will be used as a functional layer for the fuel electrode of Solid Oxide Fuel Cell (SOFC) and Solid Oxide Electrolysis Cell (SOEC). Based on t…
Our objective in this project is to build a collaboration between the two partners to design electrodes based on new hybrid metallic nanoparticles with controlled morphology and structure as the catalysts for next generation fuel cells. (AU)

A contemporary challenge in energy usage is the need of migration towards renewable sources. In this context, the production of hydrogen via water electrolysis in Proton Exchange Membrane (PEM) cells is an appealing alternative. PEM electrolysis cells are a stack of two Ti current collectors (electrodes) separated by a permeable solid membrane with catalytic materials deposited. PEM elect…
The growing concern with global warming has motivated the creation of new technologies to capture and reuse CO2, a greenhouse gas that has been progressively setting emission records year after year. Among the promising technologies to overcome this problem, the electrochemical reduction of carbon dioxide has drawn a lot of attention from the scientific community due to its versatility, w…
The use of fossil fuels for energy purposes releases substantial amount of pollutant gases into the atmosphere, such as carbon dioxide, which could result in a number of serious implications for the environment. In the light of these issues, urgent strategies need to be established to exploit new sources of energy, which must be abundant, renewable, sustainable, and resulting in minimised…

This project is associated with the study of the activity of electrocatalysts that compose the cathode of proton exchange membrane fuel cells (PEMFC). The development of the oxygen cathode of such system, where the oxygen reduction reaction (ORR) takes place, is also of large interest because its applications in metal/air batteries and in the chlor-alkali industry. In conventional PEMFC s…

Solar energy conversion systems, such as photoelectrochemical (PEC) and photovoltaic cells, have stood out as an environment-friendly approach to obtaining the two most popular energy carriers in our lives, i.e., fuel and electricity. To become the mainstream way of achieving energy, the semiconductor materials employed in these systems must absorb solar energy in an effective manner as w…
The pursuit of sustainable energy sources has spurred advances in alternative energy technologies, particularly large-scale electrocatalytic water splitting as a promising method for hydrogen production. This process involves oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), with catalytic materials at the core of electrolyzer devices. Transition Metal-based catalysts…
Many industrially significant reactions nowadays require a catalyst to be economically viable. Therefore, the design of active, stable and affordable materials is among the most important areas in the chemical science. A possible approach for fine tuning of the catalysts' properties is its modification with foreign elements by decorating with them the surface of an active material or by i…
Non-noble metal catalysts of the Fe-Nx/C type (iron atoms coordinated with nitrogen atoms, in a packaged carbon structure) and prepared using the Fe[(2,4,6-Tris(2-) pyridyl)-1,3,5-Triazine]2 2+ complex as a precursor (Fe[TPTZ]22+), have been frequently studied for their catalytic activities for several reactions, including the oxygen reduction reaction. However, despite the promising pers…
The oxygen evolution is a very important reaction that concern devices that involve clean and sustainable energy conversion, as such, solar fuel cell and metal-air batteries. Despite the considerable progress in the understanding of OER, it is still necessary to understand the reaction mechanisms and to overcome the kinetics barrier of the, nowadays known, oxygen electrocatalysts. This pr…
The solid electrolytes based on Anion Exchange Membranes (AEMs) are promising alternative for the development of a more efficient electrolytes for alkaline fuel cells. This new AFC class is usually called Anion Exchange Membrane Fuel Cell (AEMFC). In general, the AEMs are ionomeric polymers, in the same way as the proton exchange used in the Proton Exchange Membrane Fuel Cell (PEMFC) tech…
