Polymer electrolyte fuel cells (PEFCs) have recently attracted much interest due to the need for an efficient, non-polluting power source for vehicles in urban environments. Hydrogen is the most suitable fuel for a fuel cell powered vehicle, providing the highest conversion efficiency for fuel-on-board-to-electric-power and generating zero polluting emission, since water is the only product of the hydrogen/air fuel cell process. Significant efforts have been made in the last decades to investigate the direct electrochemical oxidation of alcohol and hydrocarbon fuels. Among the liquid organic fuels, methanol has promising characteristics in terms of reactivity at low temperatures, storage and handling. Nevertheless, before this technology can reach a large scale diffusion, some drawbacks related to poor electrochemical performance, high cost of fuel cell components, long term stability, etc. must be solved. In a PEFC system, high costs derive from the use of noble metal catalysts, perfluorosulfonic acid polymer electrolyte membranes, bipolar plates and auxiliary components. Therefore, the development of cost-effective and highly performing polymer electrolyte membranes, enhanced electro-catalysts and cheap bipolar plates satisfying the target requirements of high performance and durability represents an important challenge. The research is currently addressed towards cost-effective materials, such as novel hydrocarbon membranes and low precious metal loading electrodes. The key to a sustainable energy future thus lies in the development of advanced materials.
This Special Issue is intended to cover the most recent progress in advanced electro-catalysts, catalytic supports, electrodes, membranes, fillers and bipolar plates for high performance and cost-effective polymer electrolyte fuel cells, including direct alcohol fuel cells.
We look forward to receiving your contribution.

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 papers will be 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. Materials 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 1500 CHF (Swiss Francs).
