Flow type energy storage device and reaction cell for the device

A reaction cell for use in a flow-type energy storage device for storing electricity using a fluidic material, the reaction cell comprising:

• a first electric conductor plate;
• a first gasket including a first reaction region, a first corner, a second corner, a third corner and a fourth corner, the first corner being diagonal to the third corner, and the second corner being diagonal to the fourth corner, the first electric conductor plate facing one side of the first gasket;
• a membrane;
• a second gasket including a second reaction region, a first corner, a second corner, a third corner and a fourth corner, the first corner of the second gasket being diagonal to the third corner of the second gasket, and the second corner of the second gasket being diagonal to the fourth corner of the second gasket;
• and
• a second electric conductor plate facing one side of the second gasket,
• wherein the membrane is disposed between the first gasket and the second gasket,
• wherein the first to fourth corners of the first gasket correspond to the first to fourth corners of the second gasket, respectively,
• wherein each of the first reaction region and the second reaction region is a reaction region in which charge-discharge reaction of electricity is performed by the fluidic material, and each of the first reaction region and the second reaction region is occupied only by the fluidic material,
• wherein the first reaction region has a first octagonal cross-section including first to eighth sides, and the second reaction region has a second octagonal cross-section including first to eighth sides,
• wherein the first to eighth sides of the first octagonal cross-section correspond to the first to eighth sides of the second octagonal cross-section, respectively,
• wherein the first to fourth corners of the first gasket correspond to the first side, the third side, the fifth side and the seventh side of the first octagonal cross-section, respectively,
• wherein the first to fourth corners of the second gasket correspond to the first side, the third side, the fifth side and the seventh side of the second octagonal cross-section, respectively,
• wherein the first gasket includes an inlet and an outlet at only two corners among the first to fourth corners of the first gasket, and the second gasket includes an inlet and an outlet at only two corners among the first to fourth corners of the second gasket,
• wherein the inlet of the first gasket is disposed at the first corner of the first gasket corresponding to the first side of the first octagonal cross-section and the outlet of the first gasket is disposed at the third corner of the first gasket corresponding to the fifth side of the first octagonal cross-section so that the fluidic material flows diagonally in the first reaction region of the first gasket,
• wherein the inlet of the second gasket is disposed at the fourth corner of the second gasket corresponding to the seventh side of the second octagonal cross-section and the outlet of the second gasket is disposed at the second corner of the second gasket corresponding to the third side of the second octagonal cross-section so that the fluidic material flows diagonally in the second reaction region of the second gasket and diagonal flow directions of the fluidic material in the first reaction region and the second reaction region cross each other, and
• wherein the fluidic material flows in a direction from the first side of the first octagonal cross-section to the fifth side of the first octagonal cross-section in the first reaction region and flows in a direction from the seventh side of the second octagonal cross-section to the third side of the second octagonal cross-section in the second reaction region.
