Abstract
A molten carbonate fuel cell comprising a pair of conductive electrodes, an electrolyte body sandwiched between the pair of conductive electrodes and consisting essentially of an electrolyte of an alkali carbonate mixture, more than 5 mole % to 15 mole % of magnesium carbonate with respect to the alkali carbonate mixture, and an electrolyte retaining material, fuel supplying means for supplying a fuel gas to one of the pair of conductive electrodes, and oxidant supplying means for supplying an oxidant gas to the other of the pair of conductive electrodes.

A molten carbonate fuel cell comprising:
- a pair of conductive electrodes;
- an electrolyte body sandwiched between said pair conductive electrodes and consisting essentially of an electrolyte of an alkali carbonate mixture, a carbonate mixture, and an electrolyte retaining material, said carbonate mixture consisting of magnesium carbonate and at least one material selected from the group consisting of barium carbonate, calcium carbonate, and strontium carbonate, said carbonate mixture being used in 5 to 20 mol % with respect to said alkali carbonate mixture, said magnesium carbonate being used 2 to 15 mol % with respect to said alkali carbonate mixture;
- fuel supplying means for supplying a fuel gas to one of said pair of conductive electrodes;
- and
- oxidant supplying means for supplying an oxidant gas to the other of said pair of conductive electrodes.
A molten carbonate fuel cell comprising:
- a pair of conductive electrodes;
