    In fuel cell: Molten carbonate fuel cells

    Fuel cells of this type operate quite differently from those so far discussed. The fuel consists of a mixture of hydrogen and carbon monoxide generated from water and a fossil fuel. The electrolyte is molten potassium lithium carbonate, which requires an…

  • Figure 1: Schematic diagram of a zirconia oxygen sensor used to monitor automobile exhaust gases. The sensor, approximately the size of a spark plug, is fitted into the exhaust manifold of an automobile engine. The thimble-shaped zirconia sensor, sandwiched between thin layers of porous platinum, is exposed on its interior to outside air and on its exterior to exhaust gas passing through slits in the sensor shield. The two platinum surfaces serve as electrodes, conducting a voltage across the zirconia that varies according to the difference in oxygen content between the exhaust gas and the outside air.

    …play key roles in the molten carbonate fuel cell (MCFC) and the solid oxide fuel cell (SOFC). In the MCFC, nickel oxide (NO) ceramics serve as porous anodes for the molten salt (carbonate) electrolyte. In SOFCs, ceramics serve not only as the solid electrolyte (in this case, zirconia) but also…
