Special Issue Information

Dear Colleagues,

Recent advances in fuel cell and microbial fuel cell technologies have enabled enhanced control of electrochemical and bioelectrochemical processes, fostering progress in fundamental research, device miniaturization, and practical applications. The integration of computational fluid dynamics (CFD), multiphysics simulation, and artificial intelligence provides powerful tools to analyze transport phenomena, reaction kinetics, and coupled electrochemical, bioelectrochemical, fluidic behavior, enabling performance prediction, optimization, and intelligent control of advanced energy systems.

This Special Issue focuses on experimental, numerical, and data-driven studies addressing energy conversion and sustainability in fuel cells and microbial fuel cells.

The aim of this Special Issue is to showcase recent advances that combine experiments, simulation, and artificial intelligence to improve energy conversion efficiency, system reliability, 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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access semimonthly 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 2400 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.

Microfluidic fuel cells offer a promising route for portable power generation; however, scaling paper-based systems remains challenging because capillary-driven flow can limit fuel distribution and electrochemical performance. This work investigates the experimental performance and computational fluid dynamics (CFD) behavior of air-breathing paper-based microfluidic fuel cell (μFCs) stacks powered directly by commercial tequila (35 vol.% ethanol). Single cells with electrode areas ranging from 0.5 cm × 0.5 cm to 3 cm × 3 cm were evaluated to determine the optimal design, followed by the construction of 4-cell and 6-cell series-parallel stacks. The smallest electrode (0.5 cm × 0.5 cm) achieved the highest power density (0.142 mW cm−2) and open-circuit voltage (0.92 V). Scaling to a 6-cell stack increased the maximum power density to 3.20 mW cm−2 and the voltage to 1.39 V, outperforming the 4-cell configuration (1.09 mW cm−2 and 1.07 V). Computational Fluid Dynamics simulations revealed that fuel velocity decreased from 2.8 × 10−2 m s−1 near the inlet to approximately 1.0 × 10−6 m s−1 in the final cells because of porous-medium resistance, explaining the observed mass-transport limitations. The results demonstrate that tequila can be directly used as a sustainable fuel source and that optimized stack architectures significantly enhance power generation in paper-based microfluidic fuel cells.
