PURPOSE:To improve performance by setting a material of constituting an interconnector and an Si component in fuel gas and oxidation gas respectively to a specific quantity or less, so as to improve durability, electrode performance and gas permeability. CONSTITUTION:Ratio of an Si component, contained in an interconnector material buried in a through hole of a solid electrolytic layer of a fuel cell, is set to 5.0wt.%. or less. In a power generating system, in low and high temperature parts of a fuel gas introducing pipe 11 and an oxygen gas introducing pipe 17 connected to a chamber 10 arranged with the fuel cell 1 in the inside, an Si component adsorbing member 18 carrying an oxide of lead, aluminum, etc., in a porous material is arranged, to set ratio of the Si component in gas, supplied to the cell, to 1.0vol.% or less. Thus by suppressing age deterioration of durability, electrode performance and permeability of the interconnector caused by the Si component, increasing generating efficiency for a long time can be maintained. |
