Abstract
A material for a base tube of a fuel battery, comprising a mixture of at least two components selected from the group consisting CaO , ZrO2, NiO, MgO, SrO, Al2O3, TiO2, and BaO. Such material suppresses cracks of an electrolyte and also suppress leakage after rapid temperature increase and decrease, thus providing a reliable fuel battery.
Claims4
A reformed fuel battery having a porous base tube comprised of a composition comprising a complex of 9.1-26.1 wt % CaO, 20.9-60.9 wt % ZrO2 and 13.0-70.0 wt. % NiO.
A substrate material for a porous base tube of a fuel battery comprised of a multiplicity of cells connected in series, each such cell comprising a fuel electrode, an electrolyte and an air electrode laminated on the surface of the porous base tube, said substrate material comprising a complex of 9.1-26.1 wt. % CaO, 20.9-60.9 wt. % ZrO2 and 13.0-70.0 wt % NiO, provided that the NiO is present in the form of granules having a particle size of 5 μm.
