Special Issue Information
Dear Colleagues,
Since the 1970s, industrial developers and world governments have shown great interest in developing hydrogen and fuel cell technologies, the last being considered as one of a portfolio of options for clean energy sources alternative to fossil fuels. More specifically, the Proton Exchange Membrane Fuel Cell (PEMFC), using ion exchange membranes as electrolyte, is the technology of choice for portable power supplies and automotive applications. However, in view of large-scale marketing, progress still needs to be made in the interrelated areas of cost, performances and durability.
The PEMFC operation involves coupled transport phenomena and mechanisms (concerning the electrochemical reaction as well as heat, mass and charge transfer processes) occurring within and across a layered structure of media with different porosity and permeability. This makes the way PEMFCs work and age highly heterogeneous, difficult to predict and model. It appears evident that filling the gap between the state-of-art of the PEMFC technology and targets imposed by the industrial scale production will not be possible by trial and error approaches. This points out the interest of in situ and operando techniques that provide information on the local environment inside the PEMFC during operation, therefore able of producing useful inputs for forthcoming numerical studies and deeper insights into fundamental mechanisms and phenomena governing the electrochemical behavior and ageing of the membrane-electrode assembly.
This Special Issue aims to bringing together new developments in in situ and operando techniques devoted to the characterization of the PEMFC core components (i.e. membrane, electrodes, microporous and gas diffusion layers) individually or as a whole. Original research articles and reviews that provide accomplishments on the following topics, but not limited to these, are welcome:
- performance
- structure
- ageing
- ocal conditions
- water distribution and management
- temperature distribution and management
- current distribution
- transport losses

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. 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.
