Electrode for chemical reactors, in particular for redox flow batteries and redox flow battery with such an electrode

摘要

It is an electrode for chemical reactors, in particular for redox flow batteries and a redox flow battery in a stacked construction with such an electrode specified, which allows a uniform flow through the electrode layer over the entire surface. In that the inlet channels at the second ends of the electrode strips and the outlet channels at the first ends of the electrode strips are closed by liquid-tight seals, electrolyte liquid can flow over the entire length of the inlet channels over the same length of travel through the porous electrode material only in the left or right flow adjacent outlet channel. As a result of the spacing of immediately adjacent electrode strips, the inlet and outlet channels arranged on the longitudinal sides of the electrode strips are bounded laterally, while they are limited in height or thickness by the membrane and by the monopolar plates or bipolar plates, i. H. the inlet and outlet passages extend over the entire thickness of the electrode strips, so that the electrolyte liquid flows through the porous electrode material over an equal distance.
