REDOX FLOW CELL, POSITIVE ELECTRODE LIQUID FOR REDOX FLOW CELL AND NEGATIVE ELECTRODE LIQUID FOR REDOX FLOW CELL

摘要

PROBLEM TO BE SOLVED: To provide a redox flow cell which prevents increase in viscosity of an electrode liquid by simplifying structures of a barrier membrane and a redox body and preventing a redox portion in the redox body from being buried insides, a positive electrode liquid and a negative electrode liquid for redox flow cell.SOLUTION: The present invention relates to a redox flow cell 10 comprising: a barrier membrane 1 including a filter having pores; a positive electrode chamber 2 that is formed at a first side of the barrier membrane 1; a positive electrode liquid P that is injected into the positive electrode chamber 2; a negative electrode chamber 3 that is formed at a second side of te barrier membrane 1; and a negative electrode liquid N that is injected into the negative electrode chamber 3. The positive electrode liquid P contains catholyte particles in which catholyte is carried by carrier particles, and the negative electrode liquid N contains anolyte particles in which anolyte is carried by carrier particles. An average particle diameter in a group of the catholyte particles is larger than an average pore diameter of the filter. An average particle diameter in a group of the anolyte particles is larger than the average pore diameter of the filter.SELECTED DRAWING: Figure 1
