solid oxide fuel cell

In some ways solid oxide fuel cells are similar to molten carbonate devices. Most of the cell materials, however, are special ceramics with some nickel. The electrolyte is an ion-conducting oxide such as zirconia treated with yttria. The fuel for these…

…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 as anodes and as conductive connections between…
