To provide a fuel cell stack device that is applicable to miniaturization of the device and does not require a pipe for discharging off-gas up to a combustion section. A fuel cell stack device including: a first manifoldfor supplying fuel gas supplied from a reformerto a plurality of fuel cells provided in a first cell stack from above, the first manifold being connected to upper ends of the plurality of fuel cells provided in the first cell stack; and a second manifoldfor recovering fuel gas discharged from the first cell stack, and supplying the recovered fuel gas to the plurality of fuel cells provided in the second cell stack from below, the second manifold being connected to lower ends of the plurality of fuel cells provided in the second cell stack

Fuel cell stack device and fuel cell device

A solid oxide fuel cell apparatushas: multiple fuel cell units; a module casehousing multiple fuel cell units; a heat insulating materialdisposed to cover the area around the module case; a reformerfor reforming raw fuel gas using steam, thereby producing fuel gas; a combustion chamberfor combusting residual fuel gas and heating the reformer; a heat exchangerfor exchanging heat between oxidant gas and exhaust gas; and a steam generator, disposed within the heat insulating materialand on the outside of the module case, for exchanging heat between exhaust gas and water immediately after heat is exchanged in the heat exchanger, thereby producing steam.
