Abstract
A solid oxide fuel cell (SOFC) device having a gradient interconnect is provided, including a first gradient interconnect having opposing first and second surfaces, a first trench formed over the first surface of the first gradient interconnect, a second trench formed over the second surface of the first gradient interconnect, and an interconnecting tunnel formed in the first gradient interconnect for connecting the first and second trenches. A first porous conducting disc is placed in the first trench and partially protrudes over the first surface of the first gradient interconnect. A first sealing layer is placed over the first surface of the first gradient interconnect and surrounds the first trench. A membrane electrode assembly (MEA) is placed over the first surface of the first gradient interconnect and contacted with the first porous conducting disc and the first sealing layer.
