An analysis of endurance issues for MCFC

Evaluation of Ni–Ni3Al(5wt.%)–Al(3wt.%) as an anode electrode for molten carbonate fuel cell

“…The MCFC technologies are already partially entering the commercial demonstration and other technologies are developing for more efficient operation [1,2]. The MCFC is the fuel cell operated under a temperature of 650 • C, which uses Ni as an anode electrode, nickel oxide as a cathode and a molten carbonate mixture such as Li 2 CO 3 /K 2 CO 3 or Li 2 CO 3 /Na 2 CO 3 as an electrolyte.…”

“…In order to commercialize the MCFC, the lifetime of the MCFC must be about 40,000 h. For this commercialization, there remain a lot of problems to be solved. The problems are the following[2].…”

Mechanical properties of the lithium aluminate matrix for MCFC reinforced with metal oxide materials

“…Moreover, the corrosion processes often cause a permanent loss of electrolyte by forming corrosion products containing lithium or potassium [4]. The corrosion can cause over 20% of the total electrolyte loss during operation [5].…”

Effect of Dy on the corrosion of NiO/Ni in molten (0.62Li,0.38K)2CO3

“…Unfortunately, the state-of-the-art cells and cell stacks cannot reach the commercial goal of at least a 40,000 h lifetime [1]. Major problems of materials are related to the dissolution of the cathode in the carbonate melt and corrosion of the metal separator plate and the current collectors.…”
