The invention provides an electrolytic solution guide piece for a redox flow cell, which is characterized in that the guide piece is a tubular body (10) which can penetrates through a whole cell stack, and is provided with a plurality of openings in the length direction to realize fluid communication with a corresponding electrode chamber, wherein a segment of the tubular body (10) which does notneed flowing of electrolytic solution is solid. The design avoids the condition that electrolytic solution flushes a liquid inlet and a liquid outlet in a cell part in a flowing process, therefore, the phenomena of etching and liquid leakage of the electrolytic solution to the liquid inlet and the liquid outlet in a cell after the cell is used for a long term can be avoided.
