Special Issue Information

Dear Colleagues,

It is our pleasure to invite you to submit original research and review papers to this Special Issue on “Fuel Cells: Performance and Durability”. We strongly encourage you to participate in this Special Issue of Electrochem MDPI.

Fuel cells are emerging as one of the most promising technologies for clean energy generation. Fuel cells are electrochemical devices converting chemical energy to electrical and thermal energy. Depending on the type of electrolyte used, fuel cells are classified as solid oxide fuel cells (SOFCs), photocatalytic fuel cells (PFCs), proton exchange membrane fuel cells (PEMFCs), molten carbonate fuel cells (MCFCs), alkaline membrane fuel cells (AMFCs), phosphoric acid fuel cells (PAFCs), direct methanol fuel cells (DMFCs), direct ethanol fuel cells (DEFCs), biofuel cells (BFCs), and microfluidic fuel cells (MFCs). Moreover, reversible fuel cells operating as electrolyzers or fuel cells have also been developed.

Hydrogen is known as the common fuel for fuel cells. However, hydrogen is not naturally available and must be produced by decomposing hydrogenated materials such as hydrocarbons. This material decomposition that leads to hydrogen production can either happen inside or outside of the fuel cells.

This Special Issue covers current trends and future developments in fuel cell technology. Theoretical, experimental, and analytical original research, as well as reviews articles, are welcome.

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. Electrochem is an international peer-reviewed open access quarterly 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 1000 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.

Catalyst layer defects and irregularities in catalyst-coated membrane (CCM) electrodes affect the lifetime of polymer electrolyte membrane fuel cells (PEMFCs) during their operation. Thus, catalyst layer defects are important concerns for fuel cell manufacturers and prompt the development of quality control systems with the aim of fabricating defect-free electrodes. Consequently, the objective of this study is to gain a fundamental understanding of the morphological changes of real catalyst layer defects that have developed during CCM production. In this paper, missing catalyst layer defects (MCLD) formed during the decal transfer process are investigated through a nondestructive method using reflected light microscopy. The geometric features of the defects are quantified, and their growth is measured at regular time intervals from beginning-of-life (BOL) to end-of-life (EOL) until the OCV has dropped by 20% of its initial value as per a DOE-designed protocol. Overall, two types of degradation are observed: surface degradation caused by catalyst erosion and crack degradation caused by membrane mechanical deformation. Furthermore, catalyst layer defects formed during the decal transfer process were found to exhibit a higher growth rate at middle-of-life (MOL-1) and stabilize by EOL. This type of study will provide manufacturers with baseline information to allow them to select and reject CCMs, ultimately increasing the lifetime of fuel cell stacks. Full article
