Dear Colleagues,

The direct carbon fuel cell (DCFC) is a generator that converts the chemical energy of carbon directly to electricity through electrochemical oxidation of the fuel. The carbonaceous fuel (e.g., hard coals, biomass-derived biochars, active carbons, carbon black, graphite, coke) is an anode which oxidizes used oxygen from air. There are four basic types of DCFC based on the type of electrolyte: molten carbonates, solid oxygen ion conducting ceramics, aqueous and molten hydroxides. Further, composite electrolytes (so-called hybrid electrolytes) are widely used in DCFC prototypes. The purpose of this Special Issue is to present the idea of using new power generators, including direct carbon fuel cells. The work will cover all aspects that affect the efficiency, lifetime, and economy of electricity production using carbon-based fuels: types of DCFC dedicated fuels and methods of their preparation, sources (carbon black, graphite, biomass), design solutions of DCFC models and characteristics, types of electrolytes and methods of their cleaning, fuel oxidation mechanisms in DCFC, and corrosion and degradation processes of metal elements used to build the DCFC.

I invite you to exchange scientific experience and gather current data on DCFC also in aspects not mentioned above.

As scientists, we owe our planet the search for and development of new energy solutions for future generations.

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. 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.
