Entropy and Exergy Analysis in Hydrogen Energy and Fuel Cell Systems

Dear Colleagues,

The global fuel crisis is becoming increasingly severe, with the international situation being complex and liable to change; therefore, it is urgent to develop new types of energy sources and build new energy systems for maintaining energy security. In recent years, hydrogen energy and fuel cell systems have drawn increasing attention for their capacity to solve this problem.

This Special Issue focuses on the theoretical aspects of entropy generation, exergy analysis, thermodynamics, and heat transfer analysis in relation to hydrogen energy and fuel cell systems. The study of hydrogen energy mainly includes hydrogen production, storage, transmission, utilization, enabling technologies, environmental impact, and the economic and international aspects of hydrogen and hydrogen carriers. The utilization of hydrogen energy includes combustion, photochemical, fuel cells and nuclear conversion of hydrogen, hydrogen isotopes and hydrogen carriers to thermal, mechanical and electrical energies, and its applications. Research on fuel cell systems, especially solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs), is also welcome in this Special Issue.

The relationship between the properties of working fluids, operation conditions, performance and relevant phase transition, heat and mass transfer, flow field, system control, isentropic efficiency, and thermodynamic entropy and exergy analysis of systems all fall within the scope of this Special Issue.

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. Entropy 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 2600 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.
