A material for a base tube of a fuel battery, comprising a mixture of at least two components selected from the group consisting CaO, ZrO , 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.

Base material for a fuel battery

The present invention discloses a base tube for a fuel cell produced by forming a film of a fuel electrode and a film of an air electrode on a surface of the base tube, the base tube comprising a mixture of a raw material for the base tube, and coarse particles, whereby the mixture shrinks nonuniformly when sintered to increase the porosity of the base tube. Thus, the gas permeability and the cell electrical efficiency can be increased.

Base tube for fuel cell and material for base tube

The present invention discloses a base tube for a fuel cell produced by forming a film of a fuel electrode and a film of an air electrode on a surface of the base tube, the base tube comprising a mixture of a raw material for the base tube, and coarse particles of metal oxide, whereby the mixture shrinks nonuniformly when sintered to increase the porosity of the base tube. Thus, the gas permeability and the cell electrical efficiency can be increased.
