Provided is a fuel cell device capable of suppressing the amount of heat released to the outside and facilitating temperature control of power generation air and each part. A combustor 13 for combusting both an off-gas of reformed gas and an off-gas of power generation air, a combustion exhaust gas path 16 and a first air supply path 7 through which the power generation air circulates are provided. A first air heat exchanger 18 that exchanges heat with air, a fuel cell 9, and a fuel cell storage unit 10 through which off-gas of power generation air discharged from the fuel cell circulates, and a first air supply A second air supply path 8 for supplying power generation air that has circulated through the path to the fuel cell, the off-gas of the power generation air that circulates in the fuel cell storage section, and the power generation air that circulates through the second air supply path A second air heat exchanger 19 that exchanges heat between the two and a housing 30 that houses each member. The first air supply path and the second air supply path are arranged so as to cover the entire member housed in the housing. [Selection] Figure 3 |
