Advanced Membranes for Hydrogen Energy Systems: Fuel Cells and Electrolyzers

Dear Colleagues,

Membranes play a critical role in the operation, performance, and durability of both fuel cells and electrolyzers, which are key technologies in the hydrogen economy.

This Special Issue aims to highlight innovative materials, breakthrough fabrication processes, in-depth characterization methods, degradation mechanisms, and emerging membrane architectures tailored to hydrogen energy applications. We welcome high-quality submissions in the following forms:

• Original research articles
• Review papers
• Modelling and simulation studies
• Techno-economic and life cycle assessments related to membrane applications

Prospective authors may submit contributions dealing with (but are not limited to) the following:

• Proton exchange membranes (PEMs) and anion exchange membranes (AEMs)
• Ceramic and composite membranes
• Water electrolysis membranes (PEMWE, AEMWE, SOE)
• Fuel cell membranes (PEMFC, AEMFC, SOFC)
• Ion conductivity and selectivity
• Thermal and mechanical stability
• Membrane electrode assemblies (MEA) and integration
• Degradation and durability under operational conditions (temperature, current density, dynamic sollicitations, start/stop), current ripple from power electronics, gas bubble accumulation conditions
• Scale-up, cost reduction, and sustainability

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.
