An Overview and Future Perspectives of Aluminum Batteries
Giuseppe Antonio Elia,Krystan Marquardt,Katrin Hoeppner,Sebastien Fantini,Rongying Lin,Etienne Knipping,Willi Peters,Jean-Francois Drillet,Stefano Passerini,Robert Hahn +9 more
TL;DR: The evolution of the various aluminum systems, starting from those based on aqueous electrolytes to, in more details, thosebased on non-aqueously electrolytes, are described, attempting to forecast their chances to reach the status of practical energy storage systems.
Journal ArticleDOI
Development of a planar micro fuel cell with thin film and micro patterning technologies
TL;DR: In this article, a planar PEM fuel cell with a size of 1 cm × 1 ǫ cm and 200μm thickness was fabricated and stable operation was achieved at 80mW/cm2 at varying ambient conditions with dry hydrogen fuel.
Journal ArticleDOI
Planar self-breathing fuel cells
TL;DR: In this paper, a planar fuel cell based on printed circuit board (PCB) technology has been developed, which allows a completely passive, self-breathing operation of the fuel cell.
Journal ArticleDOI
Insights into the reversibility of aluminum graphite batteries
Giuseppe Antonio Elia,Ivana Hasa,Giorgia Greco,Thomas Diemant,Krystan Marquardt,Katrin Hoeppner,R. Jürgen Behm,Armin Hoell,Stefano Passerini,Robert Hahn +9 more
TL;DR: In this article, a novel study on the reaction mechanism of nonaqueous aluminum/graphite cell chemistry employing 1-ethyl-3-methylimidazolium chloride:aluminum trichloride (EMIMCl:AlCl3) as the electrolyte is presented.
Journal ArticleDOI
Stability of planar PEMFC in Printed Circuit Board technology
TL;DR: In this paper, the use of planar PEMFCs in printed circuit board (PCB) technology with a thickness of less than 3.5mm is presented, and a steady operation with this type of fuel cell was demonstrated over a week without any cell flooding.
