Special Issue Information
Summary
Fuel cells allow the direct conversion of chemically stored energy into electrical energy by means of electrochemical oxidation of gaseous, liquid or solid chemical substances. Depending on the type of electrolyte being used, we distinguish between Alkaline Fuel Cells (AFC), Phoshoric Acid Fuel Cells (PAFC), Proton Exchange Membrane Fuel Cells (PEMFC), Molten Carbonate Fuel Cells (MCFC) and Solid Oxide Fuel Cells (SOFC). The preferred fuel for fuel cells is hydrogen. But since this is not a natural resource, hydrogen has to be produced either externally or internally, i.e. outside or inside the fuel cells. The latter case leads to the very attractive concept of direct fuel cells, which are able to convert hydrocarbons into hydrogen, e.g. via internal reforming. The special issue covers current trends and future developments of fuel cell technology, including both chemical as well as electrical engineering aspects.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
