A solid O<2-> conducting material for use as an electrolyte (152) for a fuel cell, comprising: a monocrystal or polycrystal structure of the formula: A1-xBxZ, wherein, A is independently selected from lanthanum, cerium, neodymium, praseodymium, scandium or mixtures thereof; B is independently selected form strontium, calcium, barium or magnesium; x is between about 0 and 0.9999; Z is selected from the group consisting of F3-x and OcFd where F is fluorine, O is oxygen, x is between about 0 and 0.9999 and 2c+d = 3-x, wherein c is between 0.0001 and 1.5 and d is between 0.0001 and less than or equal to 3, with the proviso when A is lanthanum, Z is F3-x and x is 0, the solid material is only a monocrystal. Composite fuel cell of thin lanthanum strontium fluoride having a laminate (composite)-type structure (151, 152, 153, 154). In another aspect, the solid electrolyte for a fuel cell is a monocrystal or polycrystal structure of PbeSnfFg, where Pb is lead and Sn is tin. The use of the solid electrolyte fuel cells disclosed to generate electricity. |
