Advanced Membranes for Fuel Cells and Redox Flow Batteries: 2nd Edition

Dear Colleagues,

Renewable energy sources, such as solar and wind power, have shown great promise in relieving the worldwide dependence on fossil fuels, thereby achieving a low-carbon society. However, the intermittent nature of renewables has caused unpredictable matching between electricity supply and demand, leading to unstable and inconsistent power delivery. Thus, energy storage technologies are needed to address the challenges that come with integrating renewable energy into the power grid. Ion exchange membranes/polymer electrolytes are very important components in fuel cells and redox flow batteries, as they are responsible for ion selection and transport to react in the electrode. Fuel cells and redox flow batteries based on polymer electrolyte membranes (PEMs) play important roles in applications, such as power sources for portable electronics, distributed power generation, and electric vehicles. A good PEM must present high proton conductivity, low crossover, high selectivity, excellent mechanical strength, and mechanical, chemical, and electrochemical stability. The membrane not only affects the whole cyclability performance but also determines the economic viability of the system. Additionally, increasing customer demands for environmentally friendly membrane products has prompted scientists to search for facile, low-cost, and green production routes for novel membrane-based devices.

This Special Issue, "Advanced Membranes for Fuel Cells and Redox Flow Batteries: 2nd Edition”, will be a perfect forum to bring together the latest results obtained by key laboratories focused on membranes and membrane materials with applications in related research and development, including the synthesis, characterization, and applications of membranes.

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 250 words) can be sent to the Editorial Office for assessment.

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. Membranes 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 2200 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.
