1. A fuel cell type power generation device comprising:
a fuel cell for extracting electric power by an electrochemical reaction of a fuel; a first combustor for burning an unreacted fuel exhausted from the fuel cell; a second combustor for burning an unburned fuel exhausted from the first combustor; a reformer for producing the fuel by reforming a raw fuel and sending the produced fuel to the fuel cell; a heat-insulating package for containing the reformer and the first combustor; a first pump for supplying a gas containing an oxidizer to the first combustor; a second pump for supplying the gas containing the oxidizer to the second combustor; a controller programmed to control a supply quantity of the gas containing the oxidizer to be supplied by at least one of the first pump and the second pump; and a heat conduction member for conducting heat of the first combustor to the reformer; wherein the second combustor is provided on an outside of the heat-insulating package; and wherein the controller is programmed to perform control such that: the first pump supplies only a certain quantity of the gas containing the oxidizer to the first combustor, the certain quantity of the gas being less than a quantity for burning all of the unreacted fuel exhausted from the fuel cell; the second pump supplies a sufficient quantity of the gas containing the oxidizer to the second combustor, the sufficient quantity of the gas being a quantity for burning all of the unburned fuel exhausted from the first combustor; when a supply quantity of the raw fuel to the reformer decreases, the first pump decreases the supply quantity of the gas containing the oxidizer to be supplied to the first combustor; and when the supply quantity of the raw fuel to the reformer increases, the first pump increases the supply quantity of the gas containing the oxidizer to be supplied to the first combustor.
