The present invention relates to a method of purifying yellow phosphorus, and more particularly, to a method of effectively removing impurities from yellow phosphorus used as raw materials of a phosphoric acid to increase purity of the phosphoric acid, the method including: removing impurities from the phosphoric acid by adding an oxidizing agent to the yellow phosphorus, followed by stirring; and adding a solution including an additive having a specific functional group in a chemical structure to the yellow phosphorus from which the impurities are removed, followed by stirring.
The present invention relates to a redox flow battery and, more specifically, to: an electrolyte distribution block having a cooling function so as to a uniformly distribute an electrolyte by splitting a stack into small groups and so as to allow the electrolyte to be maintained at an appropriate temperature; and a split stack type redox flow battery comprising the same. The present invention provides an electrolyte distribution block having a cooling function, comprising: a main pipe connected to an electrolyte tank; a plurality of branch pipes branched from the main pipe and formed, in the same length, up to a connector connected to a stack; a housing for accommodating the branch pipes; and a cooling means for cooling the branch pipes.
The present invention relates to a method and an apparatus for controlling operation of a redox flow battery. The method for controlling operation of a redox flow battery according to one embodiment of the present invention comprises the steps of: measuring the initial internal resistance value of a cell module of a redox flow battery; determining whether or not the amount of change in the internal resistance value of the cell module relative to the initial internal resistance value exceeds a first reference value; and if the change amount exceeds the first reference value, controlling flow of an electric current applied to the cell module so that the potential difference between a (+) electrode and a (-) electrode of the cell module becomes smaller than a predetermined reference potential difference. The present invention has an advantage in that the efficiency of a redox flow battery can be enhanced by properly removing solid-state precipitates generated in the course of operation of the redox flow battery.
