Abstract: A method of making a solid oxide fuel cell (SOFC) includes the steps of providing a first SOFC layer laminate tape comprising a first SOFC layer composition attached to a flexible carrier film layer, providing a second SOFC laminate tape comprising a second SOFC layer composition attached to a flexible carrier film layer, and providing a third SOFC layer laminate tape comprising a third SOFC layer composition attached to a flexible carrier film layer. The first SOFC layer laminate tape, the second SOFC layer laminate tape, and the third SOFC layer laminate tape are assembled on rolls positioned along a roll-to-roll assembly line. The laminate tapes are sequentially laminated and calendered and the flexible carrier films removed to provide a composite SOFC precursor laminate that can be sintered and combined with a cathode to provide a completed SOFC. An assembly for making composite SOFC precursor laminates is also disclosed.
