Solid Oxide Fuel Cells – The Low Temperature Challenge

Dear Colleagues,

Solid Oxide Fuel Cells (SOFCs) are the most efficient technology yet invented for the conversion of the chemical energy of fuels directly into electrical energy. SOFCs are all-solid-state power systems, their heart being the oxygen-ion conducting electrolyte. At present, the state-of-the-art electrolyte is the same used in the Nernst glower lamp in 1899: yttria stabilized zirconia, which requires an operating temperature of 850-900°C, resulting in materials limitations and operating complexity. This special issue collects original research papers, reviews and commentaries focused on the challenge of lowering the operating temperature to 600-800°C (IT-SOFC, i.e. Intermediate Temperature SOFC) or even down to approximately 350°C (LT-SOFC, i.e. Low Temperature SOFC), as well as on the associated challenge of increasing lifetime. Submissions are welcome in all areas of IT-SOFC and LT-SOFC science and engineering:

• High conductivity electrolyte materials and architectures;
• Nano-structured electrodes;
• Electro-catalysis;
• Metallic interconnects and supports;
• Single cell and stack demonstration;
• Internal fuel processing;
• Balance of Plant (BOP) components;
• Modelling at the electrolyte - electrode - cell - stack - plant level;
• Life cycle and thermoeconomic analysis;
• Control and Fault Detections and Isolation (FDI) tools.

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. Catalysts is an international peer-reviewed open access monthly 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 2200 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.
