Patent number: 10658682Abstract: A fuel cell stack FS includes: a stack A that includes a single cells C that are stacked, each of the single cells including a frame 2 that holds an outer periphery of a membrane electrode assembly 1 and a pair of separators 3, 4 sandwiching the membrane electrode assembly 1 and the frame 2; and a case 50 that houses the stack A. The frame 2 comprises a protrusion 11 that protrudes outward from an outer periphery of a frame body 2A beyond an outer peripheral edge of the pair of separators 3, 4. A protrusion length of the protrusion 11 is greater than at least a gap between the frame 2 and one of the pair of separators 3, 4, and the protrusion 11 is bendable with respect to the frame body 2A. The protrusions prevent a contact between the separators 3, 4 of the single cell C and a contact between the end faces of the separators 3, 4 and the case 50 so as to prevent a short circuit of the single cell C.Type: GrantFiled: October 17, 2016Date of Patent: May 19, 2020Assignee: NISSAN MOTOR CO., LTD.Inventors: Kazuhiro Kageyama, Kazuyuki Sato

Patent number: 10519567Abstract: To improve the production yield rate of a synthesis corundum cell superior in translucency, chemical resistance or an optical component comprising calcium fluoride. On the other end side of synthetic corundum piece, spacer intervenes between the surfaces which will be bonded. The spacer is crushed flat by pressure force which effects the other end side of synthetic corundum piece in the case of heat-treatment after the temporary bonding. Thereby, the spacer does not disturb the synthetic optical contacting or chemical pressurized fusion bonding state of corundum piece.Type: GrantFiled: March 8, 2017Date of Patent: December 31, 2019Assignee: JAPAN CELL CO., LTD.Inventors: Atsushi Fukazawa, Satoshi Hayata, Kazuyuki Sato, Kiminori Omura, Hiromu Kasai
