Abstract
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 energy generation, compliantly supported within the cell chamber. The plurality planar elements each comprise a thermally conductive material having a coefficient 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.
