To provide a flow battery and a flow battery system that can reduce conduction between a negative electrode and a positive electrode.SOLUTION: A flow battery includes a positive electrode 2 and a negative electrode 3, an electrolytic solution 6, and a flow device. The electrolyte contacts the positive and negative electrodes. The flow device causes the electrolyte to flow. The flow rate of the flowing electrolyte is at least twice as large as the central portion between the positive electrode and the negative electrode than the negative electrode side portion closer to the negative electrode than the central portion.SELECTED DRAWING: Figure 1 【課題】負極と正極との導通を低減することができるフロー電池およびフロー電池システムの提供。【解決手段】フロー電池は、正極２および負極３と、電解液６と、流動装置とを備える。電解液は、正極および負極に接触する。流動装置は、電解液を流動させる。流動する電解液の流速は、正極と負極との中央部分が中央部分よりも負極寄りの負極側部分の２倍以上である。【選択図】図１
