Special Issue Information

Dear Colleagues,

Over the last few decades, and particularly due to the ever-growing interest towards the effects of climate change onto our society, the energy crisis has reached an alarming attention peak from both politicians and scientific communities. The energy crisis can be shortly defined as the concern that the world’s limited natural resources that are used to power an industrial society are diminishing as demand rises, thus causing in the near future a shortfall of energy for entire populations. In this scenario, Materials Science will play a crucial role in the forthcoming years, strongly influencing all the energy-related technologies (i.e., both for energy storage and energy production) currently under development for our future “carbon-free” society.

Therefore, the discovery of new materials and/or of new/unexpected properties in the existing ones creates exciting research opportunities and possible novel technological breakthroughs. In fact, the identification and engineering of new materials, with improved properties, lower production costs, lower environmental impact, and/or higher environmental compatibility are crucial for further developments of the next generation of energy-related technologies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

GDC-Based Infiltrated Electrodes for Solid Oxide Electrolyzer Cells (SOECs)
by Luca Spiridigliozzi, Elisabetta Di Bartolomeo, Gianfranco Dell’Agli and Francesca Zurlo

Abstract
In this work, porous complex and metal-free cathodes based on a (La0.6Sr0.4) (Cr0.5Mn0.5) O3 (LSCM) screen-printed backbone infiltrated with Ce0.9Gd0.1O2 (GDC) were fabricated for solid oxide electrolyzer cells. GDC [...] Read more.
In this work, porous complex and metal-free cathodes based on a (La0.6Sr0.4) (Cr0.5Mn0.5) O3 (LSCM) screen-printed backbone infiltrated with Ce0.9Gd0.1O2 (GDC) were fabricated for solid oxide electrolyzer cells. GDC infiltration has been optimized by structural and microstructural investigation and tested by electrochemical measurements in CO/CO2 mixtures. Infiltrated electrodes with a non-aqueous GDC solution showed the best electro-catalytic activity towards CO2 reduction, exhibiting a much lower polarization resistance, i.e., Rpol = 0.3 Ω·cm2 at 900 °C. The electrochemical performance of LSCM/GDCE in terms of Rpol is comparable to the best-performing Ni-YSZ cathode in the same operating conditions (Rpol = 0.23 Ω·cm2). Full article

Carbonate-Based Lanthanum Strontium Cobalt Ferrite (LSCF)–Samarium-Doped Ceria (SDC) Composite Cathode for Low-Temperature Solid Oxide Fuel Cells

Perovskite-based composite cathodes, La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF)–Ce0.8Sm0.2O1.9-carbonate (SDCC), were investigated as cathode materials for low-temperature solid-oxide fuel cells. The LSCF was mixed with the SDC–carbonate (SDCC) composite electrolyte at different weight percentages (i.e., 30, 40, and 50 wt %) to prepare the LSCF–SDCC composite cathode. The effect of SDCC composite electrolyte content on the diffraction pattern, microstructure, specific surface area, and electrochemical performances of the LSCF–SDCC composite cathode were evaluated. The XRD pattern revealed that the SDCC phase diffraction peaks vary according to its increasing addition to the system. The introduction of SDCCs within the composite cathode did not change the LSCF phase structure and its specific surface area. However, the electrical performance of the realized cell drastically changed with the increase of the SDCC content in the LSCF microstructure. This drastic change can be ascribed to the poor in-plane electronic conduction at the surface of the LSCF cathode layer due to the presence of the insulating phase of SDC and molten carbonate. Among the cathodes investigated, LSCF–30SDCC showed the best cell performance, exhibiting a power density value of 60.3–75.4 mW/cm2 at 600 °C to 650 °C. Full article
