“…The reaction rate on the cathode side is the limiting factor for SOFC and MCFC performance [ 15 ]. This rate depends on chemical composition [ 16 , 17 , 18 ] and microstructure [ 19 , 20 ]. In traditional SOFC technology, the main problems are the high working temperatures, which creates a complicated and expensive manufacturing process for the solid ceramic electrolyte [ 21 ].…”

High-temperature fuel cells (namely, molten carbonate and solid oxide; MCFCs and SOFCs) require the cathode to be designed to maximize oxygen catalytic reduction, oxygen ion transport, electrical conductivity, and gas transport. This then leads to the optimization of the volume fraction and morphology of phases, as they are a pathway for electrons, ions, and gases to be continuous and self-interpenetrating. Apart from the functional properties, the cathode must be mechanically stable to prevent cracking during fuel cell assembly and operation. The manufacturing process of the composite cathode was optimized to meet such requirements in this research work. The tape casting technique and further firing process were used to fabricate the cathodes. The slurry for the green tape was composed of nickel (Ni), cerium oxide doped with samarium oxide (SDC), water (solvent), and an organic binder (which becomes pore space after firing). Each of these elements is necessary for the effective transport of specific species: electrons, oxygen, ions, and gas particles, respectively. Moreover, the nickel foam was embedded into the powder-based structure to improve mechanical strength. The study involved many technological issues, such as the effect of the SDC fraction on the cathode microstructure, mechanical strength, and chemical stability at high temperatures, and also involved environmental issues.

“…Many efforts have been made to improve the stability of the cathode materials. Several alternative cathode materials have been considered such as LiFeO 2 , 8 NiO-Ce, 9 mixed oxides (LiFeO 2 -LiCoO 2 -NiO), 10 Ni-Al, 11 Ni-Nb, 12 and LiCoO 2 . 13 Currently, LiCoO 2 seems to be one of the best candidates because of its higher stability in the molten carbonate and a rate of dissolution slower than that of NiO cathodes.…”

“…In order to solve this problem, the acidic properties of the electrolyte have to be controlled (1). The addition of alkali earth, Ca, Sr and Ba to the eutectic Li/Na has a beneficial effect by increasing the basicity of the electrolyte which provokes a decrease in the NiO solubility in the electrolyte (1,5,7). Nevertheless, these additives have the inconveniency to decrease the electrolyte conductivity and thus the performances of the cell (1).…”
