Redox flow battery

A redox flow battery (1) is provided with: at least one sheet-shaped electrode (11, 13); a cell frame (20) having recesses (21, 22) for housing at least one of the electrodes (11, 13); a diaphragm (15) that is laminated on the single body frame (20) so as to close the recesses (21, 22); a bipolar current collector (40) that penetrates the cell frame (20) within the recesses (21, 22) and is electrically connected to at least one of the electrodes (11, 13); the cell frame (20) has flow paths (31-38) which communicate with the recesses (21, 22) and through which a fluid containing an active material flows so that the fluid flows in parallel with the diaphragm (15) within the recesses (21, 22), and the at least one electrode (11, 13) is disposed within the recesses (21, 22) at an angle intersecting the diaphragm (15). 氧化还原液流电池(1)具有：至少1个电极(11、13)，为薄片状；单体框架(20)，其具有收容至少1个电极(11、13)的凹部(21、22)；隔膜(15)，其层叠于单体框架(20)，以使得堵塞凹部(21、22)；双极集电部(40)，其在凹部(21、22)内贯通单体框架(20)，且与至少1个电极(11、13)电连接；单体框架(20)具有流路(31～38)，其与凹部(21、22)连通，使包含活性物
