<P>PROBLEM TO BE SOLVED: To provide a support substrate for fuel battery cells, which suppresses an expansion caused by chemical reduction, and further to provide a fuel battery cell and a fuel battery, which suppress effectively cracks and peelings of a solid electrolyte due to the expansion caused by chemical reduction of the support substrate, without having effect on controlling so as to tune the thermal expansion coefficient of the support substrate to the solid electrolyte. <P>SOLUTION: A support substrate for fuel battery cells is configured to contain iron group metals and/or oxides of the iron group metals, rare earth oxides including at least one kind of the rare earth elements (R), and Mo and/or Mo compounds, and has a gas permeability and conductivity. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
