This paper considers the dominant factors of performance decay of molten carbonate fuel cell (MCFC) stacks. Single cell operation results and the post-test analysis are discussed, and recent approaches to achieve lower decay rates and longer operation times are described. The decay rate of 1 m2 class stacks is analyzed based on single cell data. The life-limiting factors and the analysis of the decay rate are discussed based on results of stacks with conventional components, which are Ni/Al oxide dispersed strengthen anodes, in situ oxidized NiO cathodes, γ-LiAlO2 matrices with (Li0.62.K0.38)2CO3 electrolyte and AISI316L multiple cathode current collectors (perforated plate + corrugated plate). To achieve 40 000 h operation, there were three dominant factors controlling the life and the decay. These factors were the electrolyte loss, the Ni dissolution and the particle growth of LiAlO2. The reduction of the metallic surface area of the cathode current collectors, (Li/Na)2CO3 electrolyte and the α-LiAlO2 particles with uniform diameter distribution were examples of the countermeasures and showed good prospects for extending the life of MCFC.
