Abstract

To improve the mechanical properties of molten carbonate fuel cell cathode materials, pre-lithiated porous nickel plates containing 1-5 mole % of lithium were fabricated by the tape casting method, and the microstructures, mechanical properties, and performance was studied. The microstructure and pore distribution was not changed until the lithium content reached 3 mole %. The sample containing 5 mole % of lithium had patch structure on the skeleton and a smaller volume of primary pores. XRD analysis showed that lithium-containing porous nickel plates could easily form solid solutions without any undesirable byproducts after the oxidation. Both the bending strength and Young's modulus of the porous plates increased with the increase of lithium content. The average bending strengths of the samples containing 1, 3, and 5 mole % of lithium were 1.29, 1.33, and 1.49 kgf/sq mm, which were 2.9, 3, and 3.4 times higher than that of pure porous nickel plate. The Young's modulus increased ≤ 1.35 kgf/mm in the case of the 5 mole % lithium containing sample that is 5.4 times higher than that of pure porous nickel plate. The OCV of single cells using pre-lithiated cathodes were 1.065- 1.067 v, and comparable cell performance was obtained for 500 hr of single cell operation.
