Special Issue Information
Dear Colleagues,
Fuel cells are becoming a clean and efficient way to convert energy, and they can be used in portable, stationary, and transportation applications. Proton exchange membrane (PEM) fuel cells, anion exchange membrane (AEM) fuel cells, and microbial fuel cells (MFCs) are some of the most important new technologies that meet a wide range of energy needs.
Because they have a high-power density and can start up quickly, PEM fuel cells are very popular for use in cars and portable electronics. The goal of recent improvements in cathode catalysts, such as platinum-group metal (PGM) alternatives and single-atom catalysts, is to lower costs while speeding up the oxygen reduction reaction (ORR). Progress in both durable and highly conductive PEMs at the same time makes operations more stable and efficient in harsh conditions.
AEM fuel cells work in alkaline environments, which means they can use cheap materials and non-precious metal catalysts. This lowers the overall cost of the system. New developments in anion exchange membranes that have better ionic conductivity and chemical stability increases their saleability.
Microbial fuel cells use biocatalytic reactions by microorganisms to turn organic waste directly into electricity. This is a unique way to combine energy generation and wastewater treatment. Improvements in biocompatible membranes and biocathode catalysts make them much more powerful and easier to scale up.
These new catalysts and membranes are all helping to make fuel cells more efficient, less expensive, and more useful in the real world.

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. Inventions 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 1800 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.
