Abstract
A cell stack device includes a fuel cell, a first separator and a first bonding member. The fuel cell includes a solid electrolyte and a cathode that is provided on one surface of the solid electrolyte. The first separator includes a protrusion that protrudes towards the cathode. The first bonding member bonds the cathode and the first protrusion. The thickness of a first bonding member that is positioned on an outer peripheral portion is greater than the thickness of a first bonding member that is positioned at a central portion.
