  • 07/12/2022: Employees of the Laboratory of Electrochemical Devices Based on Solid Oxide Proton Electrolytes (IHTE) and the Hydrogen Energy Laboratory (UrFU) have published a new paper in International Journal of Hydrogen Energy: ‘Ba-doped Pr2NiO4+δ electrodes for proton-conducting electrochemical cells. Part 1: Structure, mechanical, and chemical properties’, being a first part of the research:

In this work, the authors investigated the physicochemical properties of materials based on layered nickelites from the viewpoint of their application as electrodes for solid oxide fuel cells and electrolyzers. It was shown that the chemical modification of the base nickelite, Pr2NiO4+δ, by a partial substitution of barium for praseodymium enhances the stability of the phase, preventing its decomposition at high temperatures and also improves its chemical compatibility with widely used proton-conducting electrolytes of a barium cerate-zirconate family. The revealed effects contribute to the improvement of quality of the electrode/electrolyte interface, which should lead to better electrode characteristics. Electrochemical verification of these assumptions is presented in the second part of the work, which will soon be sent to the same journal.

  • 11/01/2022The Journal of the American Ceramic Society (IF = 3.784) accepted for publication another article entitled “Barium-doped Sr2Fe1.5Mo0.5O6–δ perovskite anode materials for protonic ceramic fuel cells for ethane conversion”, which aims at searching for new redox-resistant electrode materials with excellent operability both in air atmospheres and hydrogen or carbon-containing fuels. From this viewpoint, one of the most studied ferrite-molybdates (with a double perovskite structure) was taken as a basis and then its composition was tailored by partial substitution of barium with strontium, Sr2–xBaxFe1.5Mo0.5O6–δ.
