摘要
An easy-to-assemble battery sealing structure, and an electrolyte circulation type battery cell frame, an electrolyte circulation type battery cell stack and an electrolyte circulation type battery including this battery sealing structure are provided. A cell frame 10 includes a battery plate-like member (bipolar plate) 11, a pair of frames 12a and 12b for holding a peripheral portion of bipolar plate 11 therebetween and pressing the peripheral portion from the front and the rear, and an annular packing 20 made of an elastic material. Frames 12a and 12b are provided with an annular groove 14 between respective surfaces of the frames facing each other, for accommodating the peripheral portion of bipolar plate 11. Packing 20 is mounted on the peripheral portion of bipolar plate 11, arranged in annular groove 14, and press-contacted between frames 12a, 12b and the peripheral portion of bipolar plate 11. Packing 20 includes a pair of legs 21 for holding the peripheral portion of bipolar plate 11 therebetween, and a base 22 connecting legs 21 together. According to this structure, a battery sealing structure sealing a space between frames 12a and 12b is formed.
