Special Issue Information
Dear Colleagues,
Alloying is one of the most powerful tools available to the designer of metallic catalysts. Alloying can be used to modify both the activity and the durability of a catalyst, both of which help to lower the cost, which is particularly important when such catalysts employ precious and/or rare metals. Catalysts for fuel cells are no different. Platinum alloys have been investigated for the last half-century, particularly for the oxygen cathode, because the oxygen reduction reaction (ORR) is in greater need of catalytic assistance than the hydrogen anode in acidic electrolytes. Alloys are also important for the hydrogen anode, because the hydrogen oxidation reaction (HOR) can be easily poisoned by carbon monoxide present in hydrogen fuels produced from natural gas. More recently, platinum alloys have also been intensively investigated for the hydrogen anode in alkaline electrolytes, because the HOR activity decreases drastically with increasing pH. Fuel cells are not limited to hydrogen as a fuel, but can also utilize alcohols and even hydrocarbons, and alloys are also extremely useful for their catalytic reactions. Despite the extensive research already devoted to such alloys, new insights continue to be revealed, and more are indeed needed to fully understand how they work. With deeper understanding, we can design even more active, more durable, lower-cost catalysts. This Special Issue entitled “Alloy Nanocatalysts for Fuel Cells” aims to bring together contributions from a diverse range of fuel cells and their associated fuels and electrolytes in order to cross-fertilize ideas that are common to all. We also welcome contributions from a wide range of viewpoints, from the applied to the fundamental.

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. 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 2700 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.
