An object of the present invention is to provide a fuel cell which prevents an unreformed fuel gas from being supplied to a fuel electrode at start-up without requiring a storage chamber for hydrogen gas and the like. In order to achieve this object, the fuel cell includes: a fuel cell stack (10) which laminates a power generation cell (16), which includes a fuel electrode layer (12), an oxidant electrode layer (13), and a solid electrolyte layer (11) sandwiched therebetween, by interposing a separator (2) between the power generation cells (16); a fuel gas supply line (40) which interposedly provides a reformer (45) supplying a reformed gas to the stacks (10); and a steam supply line (60) which interposedly provides a steam generator (41) supplying steam to an upstream side of the reformer on the fuel gas supply line, wherein start-up reformers (46a) and (46b) are interposedly provided on a downstream side of a connection portion to the steam supply line on the fuel gas supply line; start-up steam generators (43a) and (43b) are interposedly provided on the steam supply line; and the start-up reformer and the start-up steam generator are installed at a position facing start-up heating means (6a) to (6d) which operate at start-up.
