  "textContent": "A fuel cell comprising a container (20) having at least one feed port (23) and at least one exhaust port (25), and a stack of fuel cell elements (16) contained in the container (20) in such a manner that the circumferential faces of the stack of fuel cell elements (16) and the inner surfaces of the container (20) are in contact. The element (16) comprises a cathode layer (12), an anode layer (14), and an electrolyte layer (10), with the electrolyte layer (10) being interposed between the cathode (12) and anode (14) layers. A mixed gas containing a fuel gas and oxygen is fed to the fuel cell from the feed port (23), and an exhaust gas is discharged from the exhaust port (25). Packing materials (24,26) are filled in all the spaces between the feed port (23) and the stack of fuel cell elements (16) and between the stack of fuel cell elements (16) and the exhaust port (25). Any gaps between adjacent elements of the packing materials (24,26) being sized to be smaller than the quenching distance for the mixed fuel gas having an oxygen concentration within the ignition limits so that the mixed fuel gas cannot be ignited at the operating conditions of the fuel cell even if the mixed fuel gas has an oxygen concentration within the ignition limits for the mixed fuel gas.",
