Special Issue Information
Dear Colleagues,
This Special Issue explores advancements in electrocatalyst development aimed at enhancing fuel cell technology, focusing on improving catalytic activity, durability, and energy efficiency. As an essential electrocatalytic process in fuel cells, oxygen reduction reaction (ORR) electrodes in fuel cells face challenges, including the low activity and stability of non-precious catalysts, as well as issues with mass transport and water management. Additionally, the high cost and degradation of platinum-based catalysts, coupled with difficulties in optimizing electrode structure and scalability, hinder the efficiency and practicality of fuel cells. In response, substantial efforts have been dedicated to developing and optimizing a range of catalysts, including non-precious metals, alloys, and nanostructured materials, to achieve high catalytic activity and durability under practical operating conditions. Recent innovative strategies involve refining the surface structure, electronic properties, and composition of catalysts to boost ORR performance. Research also includes advances in atomically dispersed catalysts that enhance durability and minimize degradation. This issue highlights recent breakthroughs in catalyst synthesis, mechanistic studies of ORR, and design principles that promise to advance sustainable and scalable fuel cell technologies for applications in transportation, portable electronics, and renewable energy systems.
Potential topics include, but are not limited to, the following:
- ORR catalysts;
- Fuel cells;
- Platinum group metal catalysts;
- Non-precious metal catalysts;
- Nanomaterials;
- Alloy catalysts;
- Dispersive single-atom catalyst;
- Reaction mechanisms;
- Catalysis deactivation.

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. Batteries 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.
