<P>PROBLEM TO BE SOLVED: To provide an electrochemical element such as a solid oxide fuel cell element having high efficiency, capable of being started and stopped in a short time and operable at low temperatures. <P>SOLUTION: This electrochemical element is so structured that parts excluding one-side ends on the side of one-side edges of a plurality of fuel electrode-solid polymer layer stack tubes 21 each having an outside diameter not greater than 2 mm and comprising a linear cylindrical fuel electrode tube and a solid polymer layer formed on a part excluding one-side end out of a peripheral surface of the cylindrical fuel electrode tube are inserted into a plurality of through-holes provided for a non-baked air electrode body used as a part of an air electrode body 11; a material for an air electrode used as the other part of the air electrode body 11 is filled in a space between the peripheral surfaces of the fuel electrode-solid polymer layer stack tubes 21 and the circumferential surfaces of the through-holes; and the non-baked air electrode body and the material for an air electrode are baked. <P>COPYRIGHT: (C)2007,JPO&INPIT |
