NºPublicación: EP3444884A1 20/02/2019

Solicitante:
FRAUNHOFER GES FORSCHUNG [DE]

Resumen de: EP3444884A1

Es wird eine elektrisch leitfähige Kontaktplatte für Redox-Flow-Zellen vorgeschlagen, welche aus wenigstens einem thermoplastischen Polymer mit hierin eindispergierten, elektrisch leitfähigen Partikeln auf der Basis von Graphit gebildet ist, wie sie als Bipolarplatte in Redox-Flow-Zellen Anwendung finden kann. Um bei einer möglichst hohen elektrischen Leitfähigkeit gleichwohl für einen möglichst geringen Anteil an elektrisch leitfähigen Füllpartikeln und somit für eine gute Verschweißbarkeit der Kontaktplatte zu sorgen, sieht die Erfindung vor, dass zumindest einige der elektrisch leitfähigen Partikel von im Wesentlichen folienförmigen Graphitplättchen aus expandierter Graphitfolie gebildet sind, wobei die Kontaktplatte aufgrund Schmelzfähigkeit schweißbar ist. Darüber hinaus kann die Kontaktplatte nicht folienförmige Partikel auf der Basis von Graphit enthalten, insbesondere in Form vom Kohlenstoff-Nanoröhren. Die Erfindung betrifft ferner ein Verfahren zur Herstellung einer solchen Kontaktplatte sowie eine Redox-Flow-Zelle mit einer derartigen Kontaktplatte.
