    • A seal is provided for use in a solid oxide fuel cell, wherein the seal is formed of alternating adjacent layers of a fiber tow material and a foil material. A solid oxide fuel cell stack is also disclosed and is formed of repeating cell units, each cell unit having a plurality of fuel cell stack components defining opposed component surfaces, and the seal as described above positioned between the opposed component surfaces. A process is also provided for manufacturing a composite seal for a solid oxide fuel cell, and the process including the steps of: (a) feeding a quantity of spooled fiber tow material through an inert bonding agent to form a coated fiber tow material; (b) winding the coated fiber tow material about a mandrel to form a wound layer of fiber tow material; (c) feeding a quantity of spooled foil material about the wound layer of fiber tow material to form a wound layer of foil material; and (d) repeating steps (a) through (c) until forming a composite seal having desired thickness and width.
