Patent number: 9728827Abstract: Each air battery stacked in a battery pack includes a cathode layer, an anode layer, an electrolyte layer and a frame member having electrical insulation properties and surrounding at least outer circumferences of the electrolyte layer and the cathode layer. The cathode layer includes a fluid-tight air-permeable member located at a cathode surface thereof and having, when viewed in plan, an outer circumferential edge portion situated outside of the outer circumference of the electrolyte layer. The frame member includes a holding portion located a cathode side thereof so as to hold the outer circumferential edge portion of the fluid-tight air-permeable member. The outer circumferential edge portion of the fluid-tight air-permeable member is adapted as a compressed region to which a compressive load is applied in a thickness direction thereof. By this structure, it is possible to achieve both of thickness reduction and high electrolyte sealing performance.Type: GrantFiled: January 21, 2013Date of Patent: August 8, 2017Assignee: Nissan Motor Co., Ltd.Inventors: Atsushi Miyazawa, Tomokatsu Himeno, Keita Iritsuki, Mori Nagayama
