Abstract
A composite active electrolyte-matrix tape, single laminated active electrolyte-matrix tapes laminate, single electrolyte matrix/cathode tapes laminate, and single composite active electrolyte-matrix/cathode tapes laminate, all in the form of a single flexible sheet for use as fuel cells components, and process for producing same in situ. These components reduce the number of components necessarily handled in fuel cell assembly. The composite active electrolyte-matrix tape provides a major portion or all of the active electrolyte required by the entire cell for operation. The electrolyte matrix/cathode tapes laminate provides a supported electrolyte matrix structure resistant to cracking and fracture. Active electrolyte may also be added to either the electrolyte matrix, to the cathode, or to both tapes in the electrolyte matrix/cathode laminate to provide a major portion or all of the active electrolyte for cell operation. The invention is suited for molten alkali metal carbonates fuel cells.
