PURPOSE:To provide a method and device for controlling the temp. of the catalyst layer of a fuel reformer for fuel battery use reducing the loss of heat and power, even if there is an excessive off-gas emission from the battery affording a heating source for heating the catalyst layer in a reaction pipe of a fuel reformer. CONSTITUTION:There is provided an off-gas emission system provided with a flow rate control value branched from an off-gas supply system for supplying an off-gas from a fuel battery to the burner of a fuel reformer, a flow rate control valve is controlled, so that the temp. of a catalyst layer in a reaction pipe becomes a predetermined value, so as to regulate the flow rate of the off-gas to be supplied to the burner, a ratio control is made of combustion air flow rate, so that an air/fuel ratio of the off-gas flow rate to the combustion air flow rate becomes a predetermined value and the off-gas is burned by the burner to control the temp. of the catalyst layer. |
