摘要： A bipolar plate disposed between a positive electrode and a negative electrode of a redox flow battery has, in a surface of the bipolar plate facing at least one of the positive electrode and the negative electrode, at least one groove through which an electrolyte flows. The groove has a pair of sidewalls facing each other in a cross section orthogonal to a direction in which the electrolyte flows. The groove has a narrow portion in which a distance between the sidewalls decreases in a depth direction of the groove, the narrow portion being provided in at least a part of the groove in the depth direction.

摘要： An introduction channel and a discharge channel, which is independent of and not connected to the introduction channel, are provided in each of a surface of a cell frame that faces a positive electrode and a surface of the cell frame that faces a negative electrode. The introduction channel introduces an electrolyte to a corresponding one of the electrodes. The discharge channel discharges the electrolyte from the corresponding one of the electrodes. The introduction channel includes an introduction rectifying groove and a plurality of introduction branch grooves that are connected to the introduction rectifying groove and spaced from each other. The discharge channel includes a discharge rectifying groove and a plurality of discharge branch grooves that are connected to the discharge rectifying groove and spaced from each other. The introduction branch grooves extend toward the discharge rectifying groove and the discharge branch grooves extend toward the introduction rectifying groove. Separation distances X between the introduction rectifying groove and the discharge branch grooves and separation distances Y between the discharge rectifying groove and the introduction branch grooves are in a range from 1 mm to 30 mm.

摘要： A submarine solid cable which contains an insulating oil inhibited from moving during use of the cable; and a process for producing the cable. The process for submarine solid cable production includes infiltrating a medium-viscosity insulating oil into an insulating layer formed by winding an insulating tape including a resinous film on the periphery of a conductor. An insulating tape including a resinous film is wound on the periphery of a conductor (1) to form an insulating layer. This insulating layer is impregnated with an insulating oil having a medium or higher viscosity. The resinous film is thus swelled to narrow the infiltration passage impregnated with the insulating oil. According to the process, an insulating-oil infiltration passage can be secured during impregnation with the insulating oil, and the infiltration passage is in a narrowed state to inhibit insulating-oil movement during use of the cable. Thus, the cable has excellent insulating properties.
摘要翻译：在使用电缆期间，包含绝缘油的海底固体电缆被阻止移动; 以及电缆的制造工序。海底固体电缆的制造方法包括将中等粘度的绝缘油浸渍在通过在导体的周围卷绕包含树脂膜的绝缘带而形成的绝缘层。包含树脂膜的绝缘带缠绕在导体（1）的周边上以形成绝缘层。该绝缘层用具有中等或更高粘度的绝缘油浸渍。因此树脂膜膨胀以使浸渍有绝缘油的渗透通道变窄。根据该方法，在浸渍绝缘油的同时可以确保绝缘油浸渗通道，并且渗透通道处于变窄状态，以防止电缆使用过程中的绝缘油运动。因此，电缆具有优异的绝缘性能。

摘要： There is provided a frame body used for a cell of a redox flow battery, that can improve heat dissipation of an electrolyte in a slit and can suppress rise of the temperature of the electrolyte. It is a frame body used for a cell of a redox flow battery, comprising: an opening formed inside the frame body; a manifold allowing an electrolyte to pass therethrough; and a slit which connects the manifold and the opening and forms a channel of the electrolyte between the manifold and the opening, the slit having a pair of sidewalls facing each other in a cross section orthogonal to a direction in which the electrolyte flows, the slit having, at at least a portion thereof in the slit's depthwise direction, a width narrowing portion allowing the sidewalls to have a spacing narrowed in the depthwise direction.
