<P>PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell which can prevent air and fuel gas from leaking (flowing out) from respective collectors, and can facilitate manufacturing. <P>SOLUTION: The solid electrolyte fuel cell 10 supplies fuel gas to a membrane-electrode assembly 12 through a fuel electrode collector 16, and generates power by supplying air to the membrane-electrode assembly through an air electrode collector 21. The solid electrolyte fuel cell includes the fuel electrode collector formed of a foam of conductive metal or a mesh member of conductive metal. The fuel electrode collector includes an outer circumference part 27 arranged along an outer circumference of the fuel electrode collector, and an inside 28 arranged on an inner side of the outer circumference part, and is formed so that a density ρ1 of the outer circumference part is higher as compared with a density ρ2 of the inside. <P>COPYRIGHT: (C)2011,JPO&INPIT |
