<P>PROBLEM TO BE SOLVED: To realize improvement in power generation efficiency and improvement in durability by uniformizing the temperature in lamination direction of a fuel cell stack. <P>SOLUTION: This is a supply method of an oxidizer gas of a solid oxide fuel cell, in which a fuel cell stack 1 is constructed, by laminating a plurality of power generation cells 5 where a fuel electrode layer and an air electrode layer are arranged on both sides of a solid electrolyte layer and power generation reaction is caused, by supplying a fuel gas and an oxidizer gas to each power generation cell 5. The amount of oxidizer gas supplied to the power generation cells 5, located at an intermediate stage of the fuel cell stack 1, is made larger than the standard amount, and the amount of the oxidizer gas supplied to the power generation cells 5, located at the end parts of the fuel cell stack 1, is made smaller than the standard amount. <P>COPYRIGHT: (C)2008,JPO&INPIT |
