Patent number: 11664517Abstract: A planar SOFC cell unit is formed from a plurality of planar elements (1100, 1200, 1300) stacked one above another. The cell unit encloses a cell chamber (1400) that includes a solid oxide fuel cell (2000) configured for electro-chemical generation, compliantly supported within the cell chamber. The plurality planar elements each comprise a thermally conductive material having a co-efficient of thermal conductivity that is a least 100 W/mK such as aluminum or copper. The planar elements are thermally conductively coupled to each other to provide a continuous thermally conductive pathway that extends from perimeter edges of the cell chamber to perimeter edges of the plurality of planar elements. An SOFC stack comprises a plurality of the planar SOFC cell units stacked one above another.Type: GrantFiled: August 20, 2021Date of Patent: May 30, 2023Assignee: UPSTART POWER, INC.Inventors: Nathan Palumbo, Joshua E.

Patent number: 9640965Abstract: A cable gland assembly for attaching a shielded cable to an electronic enclosure includes a cable gland housing enclosing and in electrical contact with exposed cable shielding of the shielded cable and providing an electrically conductive pathway between the cable shielding and the electronic enclosure. The cable gland housing further encloses a shield pressure ring disposed to hold the exposed cable shielding in contact with the cable gland housing, a weather gasket, and an exposed portion of a cable strength member. The cable gland assembly includes environmental molding disposed within the cable gland housing to bond to and fix in place the exposed cable shielding, shield pressure ring, weather gasket, and exposed cable strength member. An outer molding is disposed around the cable gland housing.Type: GrantFiled: March 25, 2016Date of Patent: May 2, 2017Assignee: Protonex Technology CorporationInventors: David N. Long, Paul W.
