A fuel cell power plant is provided with a reformer (18) producing a reformate gas and a carbon monoxide removal device (1) removing carbon monoxide from the reformate gas as a result of catalytic reactions. When the carbon monoxide removal device (1) is operating at a low temperature, a heat exchanger (10) supplies gaseous heat transmitting medium to a heat exchange portion (5) of the carbon monoxide removal device (1) and warms the catalyst using heat exchange operations with the catalyst in the carbon monoxide removal device (1). The pressure regulation valve (12) regulates the pressure of the gaseous heat transmitting medium and maintains the temperature of the catalyst between the catalyst activation temperature and the predetermined upper limiting temperature of the catalyst in order to employ latent heat resulting from the heat of condensation of the steam for heating the catalyst. <IMAGE> |
