  • Molten-carbonate fuel cells (MCFCs) are high-temperature fuel cells, that operate at temperatures of 600°C and above. Molten carbonate fuel cells (MCFCs) are currently being developed for natural gas and coal-based power plants for electrical utility, industrial, and military applications. MCFCs are high-temperature fuel cells that use an electrolyte composed of a molten carbonate salt mixture suspended in a porous, chemically inert ceramic matrix of beta-alumina solid electrolyte (BASE). Since they operate at extremely high temperatures of 650°C (roughly 1,200°F) and above, non-precious metals can be used as catalysts at the anode and cathode, reducing costs. Improved efficiency is another reason MCFCs offer significant cost reductions over phosphoric acid fuel cells (PAFCs). Molten carbonate fuel cells can reach efficiencies approaching 60 percent, considerably higher than the 37-42 percent efficiencies of a phosphoric acid fuel cell plant. When the waste heat is captured and used, overall fuel efficiencies can be as high as 85 percent. Unlike alkaline, phosphoric acid, and polymer electrolyte membrane fuel cells, MCFCs don't require an external reformer to convert more energy-dense fuels to hydrogen. Due to the high temperatures at which MCFCs operate, these fuels are converted to hydrogen within the fuel cell itself by a process called internal reforming, which also reduces cost. Molten carbonate fuel cells are not prone to carbon monoxide or carbon dioxide "poisoning" —they can even use carbon oxides as fuel—making them more attractive for fueling with gases made from coal. Because they are more resistant to impurities than other fuel cell types, scientists believe that they could even be capable of internal reforming of coal, assuming they can be made resistant to impurities such as sulfur and particulates that result from converting coal, a dirtier fossil fuel source than many others, into hydrogen. The primary disadvantage of current MCFC technology is durability. The high temperatures at which these cells operate and the corrosive electrolyte used accelerate component breakdown and corrosion, decreasing cell life. Scientists are currently exploring corrosion-resistant materials for components as well as fuel cell designs that increase cell life without decreasing performance.
  • Die Schmelzkarbonatbrennstoffzelle (engl. Molten Carbonate Fuel Cell, MCFC) ist eine Hochtemperatur-Brennstoffzelle, die bei einer Betriebstemperatur zwischen 580 °C und 675 °C arbeitet. Als Elektrolyt verwendet dieser Zellentyp eine Alkalicarbonat-Mischschmelze aus Lithium- und Kaliumcarbonat.
  • Les piles à combustible à carbonate fondu, ou MCFC (d'après l'acronyme de l'appellation anglaise Molten-carbonate fuel cell) sont des piles à combustible fonctionnant à des températures à partir de 600 °C et au-delà. Elles démontrent les plus grandes efficacités parmi tous les types de piles à combustible, y compris les piles à combustible à oxyde solide, les piles à combustible à membrane d'échange de protons et les piles à combustible à acide phosphorique, et ne sont pas sujettes aux problèmes de matériaux à haute température qui affectent la technologie des piles à combustible à oxyde solide.
  • Molten Carbonate Fuel Cell (MCFC) is een brandstofcel werkend met gesmolten carbonaat (CO3) als elektroliet. Het ionentransport vindt plaats met behulp van carbonaat-ionen, de katalysator voor de ionisatie van waterstof is nikkel of nikkeloxide.
  • Ogniwo paliwowe ze stopionym węglanem, MCFC (ang. Molten Carbonate Fuel Cell) - to rodzaj wysokotemperaturowego ogniwa paliwowego, pracującego przy t=600°C i wyżej. Ogniwa te powstały w latach sześćdziesiątych XX w. i były bardzo drogie ze względu na elektrody wykonane z metali szlachetnych. W latach siedemdziesiątych XX w. elektrody zaczęto wykonywać z niklu (Ni) i jego tlenku (NiO) oraz chromu (Cr). Dzięki temu udało się obniżyć nie tylko cenę, ale i zwiększyć moc z 10 mW/cm do 150 mW/cm. Czołowym wytwórcą ogniw MCFC w Stanach Zjednoczonych jest firma FuelCell Energy.
  • Ergimiş karbonat yakıt hücresi (kısaca EKYH), yüksek sıcaklık yakıt hücresi olup 600C ve üstünde çalışır. Tüm yakıt hücreleri içinde verimi en yüksek olandır. EKYH ler, daha çok doğal gaz ve kömür esaslı elektrik santralleri, endüstriyel ve askeri uygulamalarda kullanıma yönelik olarak geliştirilmektedir. Ergimiş karbonat tuz karışımından meydana gelen elektrolit, poröz ve kimyasal olarak inert bir seramik üzerinde asılı durur. Çok yüksek sıcaklıklarda çalışıldığından anot ve katotta, katalizör olarak kıymetli metal kullanma zorunluluğu yoktur, ki bu da maliyeti düşürür.
