Abstract
A fuel cell includes a cell having a solid oxide electrolyte between electrodes. The cell has a first coefficient of thermal expansion. A metallic support is in electrical connection with one of the electrodes. The metallic support includes a metal substrate and a compliant porous nickel layer that is bonded to the metal substrate between the cell and the metal substrate. The metal substrate has a second coefficient of thermal expansion that nominally matches the first coefficient of thermal expansion of the cell. The metal substrate has a first stiffness and the compliant porous nickel layer has a second stiffness that is less than the first stiffness such that the compliant porous nickel layer can thermally expand and contract with the metal substrate.
