A long-life molten carbonate fuel cell in which outflow of an electrolyte in an electrolyte body (13) sandwiched between a pair of electrodes is reduced to suppress an increase in internal pressure of the electrolyte body (13) and generation of a gas crossover which are caused by the outflow of the electrolyte is disclosed. The molten carbonate fuel cell includes a pair of conductive electrodes (11, 12), an electrolyte body (13) sandwiched between the pair of electrodes (11, 12) and constituted by a porous body containing as a filler at least two heterogeneous particles selected from the group consisting of LiA l xOy (4.5 </= x </= 5.5 and 7.25 </= y </= 8.75), LiA l aOb (0.89 </= a </= 1.11 and 1.80 </= b </= 2.20), lithium zirconate, and stabilized zirconia, and an electrolyte consisting of an alkali carbonate mixture impregnated in the porous body, fuel gas supplying member (22) for supplying a fuel gas (21) to one of the pair of electrodes (11, 12), and an oxidant gas supplying member (25) for supplying an oxidant gas (24) to the other of the pair of electrodes (11, 12). <IMAGE> |
