Special Issue Information

Dear Colleagues,

The water-splitting technology that appears today as the most appropriate for interfacing to electrical grids sharing a large fraction of renewable energy is polymer electrolyte membrane water electrolysis (PEMWE). The main advantages of PEMWE over the competitive alkaline electrolysis systems are essentially regarding the higher operating current density, better efficiency, and dynamic behavior in terms of rapid response, fast start-up, and wider operating range. While alkaline electrolysers are advantageous when it comes to their longevity and costs, proton exchange membrane electrolysis technology is favorable in terms of safety and high gas purity with the possibility to operate under high differential pressure conditions. It is widely considered that one of the main disadvantages of PEM technology is the high overpotential of the oxygen evolution reaction requiring the use of high loading noble metal catalysts. According to several cost analyses, today, the impact of catalyst cost on the overall system cost is relevant being it is close to that of the expensive titanium-based bipolar plates, requiring special coatings, and the balance-of-plant.

This Special Issue is intended to cover the most recent progresses in advanced electro-catalysts, from the synthesis and characterization to the evaluation of corrosion resistance and catalytic activity, in order to gain insights towards the development of high-performing PEM electrolyser.

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 papers will be 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 1600 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.
