摘要： A cell stack for redox flow cells the reliability of which is enhanced for a long time without adhering a dipolar plate and an electrode. The cell stack (1) for redox flow cells is a laminate of cell frames (2), electrodes (3, 4), and diaphragms (5). The cell frame comprises a framework (2A) and a dipolar plate (9) provided inside the framework. The electrodes contact the dipolar plate by a clamping force without being adhered to the dipolar plate. If the electrodes are compressed to a thickness equivalent to the step difference between the framework and the dipolar plate, a preferable repulsive force is more than 15kPa and less than 150kPa (more than 0.153kgf/cm 2>and less than 1.53kgf/cm 2>).

摘要： Provided are a battery cell that can be produced efficiently. A frame body of each cell frame of a battery cell includes an inner peripheral recessed portion formed by reducing a thickness of a peripheral portion that surrounds an entire perimeter of the penetrating window so that the peripheral portion has a smaller thickness than other portions of the frame body. A bipolar plate of the battery cell includes an outer peripheral engaging portion that engages with the inner peripheral recessed portion, the outer peripheral engaging portion being a portion having a particular width and extending throughout an entire outer periphery of the bipolar plate. The battery cell includes a disrupting structure that disrupts a leak channel that serves as an escape route for the electrolyte, the leak channel causing the inlet slit and the outlet slit to be in communication with each other and being formed between an outer periphery of the inner peripheral recessed portion and an outer periphery of the outer peripheral engaging portion when the cell frames are viewed from front.

摘要： An electrolyte-circulating battery according to the present invention includes a cell frame including a bipolar plate in contact with an electrode that forms a battery cell, and a frame that surrounds a peripheral edge of the bipolar plate; and a sealing member that is disposed on the frame and that prevents an electrolyte supplied to the battery cell from leaking out of the frame. The frame has a seal groove in which the sealing member is fitted. The seal groove includes a narrow section that causes the sealing member to elastically deform to prevent the sealing member from becoming detached from the seal groove. The narrow section has a width that is uniform in a depth direction of the seal groove.
