Abstract
A burner combustion chamber (), a reformer catalyst () to which burner combustion gas is fed, and a heat exchange part () for heating the air fed to the burner () are provided. When the temperature of the reformer catalyst () exceeds the allowable catalyst temperature (TX) or when it is predicted the temperature of the reformer catalyst () will exceed the allowable catalyst temperature (TX), the air circulation route for guiding air to the burner () is switched from a high temperature air circulation route () for guiding air heated by the heat exchange part () to the burner () to a low temperature air circulation route () for guiding air not flowing within the heat exchange part () and lower in temperature than the air heated at the heat exchange part () to the burner ().
