Molten carbonate fuel cell components have been found sometimes to experience accelerated corrosion in the presence of molten electrolyte and fuel and oxidant gases. Development of long-term cost effective cell component materials hence plays an important role in the commercialization of fuel cell power plants. Thermodynamically stable coatings and corrosion resistant materials have been based on accelerated corrosion tests. Aluminum rich wet seal coatings have also been to minimize wet seal corrosion and electrolyte migration.
