Patent number: 10547061Abstract: A fuel cell stack includes a structural endplate having an exterior surface. An insulator plate contacts an interior surface of the structural endplate located on an opposite surface of the endplate relative to the exterior surface. A collector plate contacts the insulator plate on an opposite side of the insulator plate relative to the structural endplate. A pocket plate is located on an interior side of the collector plate located on an opposite side of the insulator plate relative to the structural endplate. The collective plate is received in a pocket of an exterior side of the pocket plate. The exterior side is adjacent the collector plate and closer to the structural endplate than an opposite side of the pocket plate.Type: GrantFiled: December 22, 2016Date of Patent: January 28, 2020Assignee: PLUG POWER INC.Inventors: James D'Aleo, Charles Russell Elder

Patent number: 10381658Abstract: A fuel cell stack includes a fluid flow plate at an outer end, a sealing member contacting the fluid flow plate and a gas diffusion layer, and a catalyst layer inside the gas diffusion layer. A membrane is located at a central location between the catalyst layer and a second catalyst layer. The fluid flow plate includes a channel for receiving a portion of a perimeter of the gas diffusion layer.Type: GrantFiled: December 22, 2016Date of Patent: August 13, 2019Assignee: PLUG POWER INC.Inventors: Charles Russell Elder, James D'Aleo

Patent number: 10215314Abstract: A threaded tubular connection including a first tube and a second tube is provided. The first tube includes a pin member which extends from an end of a main body of the first tube to a terminal end of the first tube. The second tube includes a box member which extends from an end of a main body of the second tube to a terminal end of the second tube. A cross-sectional area of a pin critical cross-section is within approximately ±5% of cross-sectional area of a box critical cross-section of the box member. The cross-sectional areas of each of the pin and box critical cross-sections are within approximately ±5% of the sum of the cross-sectional areas of a box intermediate critical cross-section of the box member and a pin intermediate critical cross-section of the pin member.Type: GrantFiled: August 23, 2010Date of Patent: February 26, 2019Assignee: VALLOUREC OIL AND GAS FRANCEInventors: Russell Elder, Bertrand Maillon

Patent number: 10077612Abstract: In a screw joint for a steel pipe, a taper angle of a tapered surface of a pin is substantially the same as a taper angle of a tapered surface of a box. In addition, the pin and the box interfere with each other in a radial direction while a seal surface of the pin and a seal surface of the box contact each other in a process of make-up between a male screw portion and a female screw portion, and at least apart of the seal surface of the pin comes into close contact with at least a part of the seal surface of the box over the entire circumference. Moreover, a contact pressure amplification mechanism, which increases a contact pressure between the seal surface of the pin and the seal surface of the box at the completion of the make-up, is further provided.Type: GrantFiled: September 11, 2013Date of Patent: September 18, 2018Assignees: NIPPON STEEL & SUMITOMO METAL CORPORATION, VALLOUREC OIL AND GAS FRANCEInventors: Yousuke Oku, Tatsuya Yamamoto, Masaaki Sugino, Russell Elder

Patent number: 8931809Abstract: A threaded tubular connection includes a first tube and a second tube. The first tube includes a pin member and the second tube includes a box member. A cross-sectional area of a pin critical cross-section is within approximately ±5% of cross-sectional area of a box critical cross-section of the box member. The cross-sectional areas of each of the pin and box critical cross-sections are within approximately ±5% of the sum of the cross-sectional areas of a box intermediate critical cross-section of the box member and a pin intermediate critical cross-section of the pin member. In a made-up state, a first seal surface on the pin engages a second seal surface on the box in a radial direction so as to form an off-center fluid tight seal that extends in an axial direction of the threaded tubular connection.Type: GrantFiled: September 21, 2012Date of Patent: January 13, 2015Assignees: Vallourec Oil and Gas France, Nippon Steel & Sumitomo Metal CorporationInventors: Russell Elder, Bertrand Maillon, Yousuke Oku
