Monopolar plate component for chemical reactors, in particular for redox flow batteries, process for the preparation of a Monopolarplattenbauteils and redox flow battery with such a Monopolarplattenbauteil

摘要

There is provided a monopolar plate member for chemical reactors, particularly for redox flow batteries, a method for producing such a monopolar plate member, and a redox flow battery having such a monopole plate member which, compared with the prior art, has lower contact resistance between monopolar plate and current collector demonstrate. For this purpose, an electrically conductive contact structure, for. As a copper grid, pressed into the monopolar plate, so that only parts of the contact structure of the graphite polymer composite material of the monopolar protrude out. Subsequently, pantograph and monopolar plate are pressed together with a solder paste layer between them and soldered together by means of solder. As an alternative embodiment, contact structure may already be coated with solder when it is pressed into the bipolar plate.
