Proton-Conducting Oxides for Electrochemical Application: Progress and Prospects

Dear Colleagues,

Solid oxide electrolytes with pronounced proton transport constitute serious competitors to conventional oxygen-conducting electrolytes from the applied point of view. The higher mobility of protons and their low migration barrier allow to reach excellent ionic conductivity over a wide temperature range (300–700 °C). This feature, coupled with a rational selection of conjunct materials and technological innovations, enables the design of electrochemical devices with very high performance, promising efficiency and wide functionality, such as energy conversion (protonic ceramic fuel and electrolysis cells, reversible solid oxide cells), chemical conversion (membrane reactors), analytical detection (sensors), hydrogen separation and compression (electrochemical pumps). Although many promising results have been reached in the past few years, the development of new materials and the search for new “structure–properties–performance” relationships remain the focus of undiminished interest in scientists.

The Special Issue “Proton-Conducting Oxides for Electrochemical Application: Progress and Prospects” aims at discussing recent research on these unique materials, their functional properties, and electrochemical applications. Scientists working in these fundamental and applied fields are invited to contribute to this Special Issue.

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 250 words) can be sent to the Editorial Office for assessment.

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. Materials 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 2600 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.
