In a method for starting up a fuel cell system, reforming is reliably performed from an early stage to more reliably prevent the oxidative degradation of the anode. A method for starting up a fuel cell system including a reformer having a reforming catalyst layer, for reforming a hydrocarbon-based fuel to produce a hydrogen-containing gas, and a high temperature fuel cell for generating electric power using the gas, wherein a) a temperature condition of the catalyst layer under which the fuel at a flow rate lower than a fuel flow rate at the completion of start-up can be reformed, and a temperature condition of the catalyst layer under which the fuel at the flow rate at the completion of start-up can be reformed are previously found, b) the temperature of the catalyst layer is increased, while the temperature of the catalyst layer is measured, c) the measured temperature of the catalyst layer is compared with at least one of the temperature conditions to determine the flow rate of the fuel that can be reformed at a point of time when the measurement is performed, d) the fuel at the determined flow rate is supplied to the catalyst layer and reformed, and the reformed gas is supplied to the anode of the fuel cell, when the determined flow rate exceeds the present value of the fuel flow rate, and the steps c and d are repeated until the feed rate of the fuel to the catalyst layer becomes the flow rate at the completion of start-up. Also provided is a fuel cell system appropriate for this method. |
