ABSTRACT:
A reformer for a fuel cell system, and a method of controlling the reformer. The reformer includes a cylindrical reforming catalyst; a burner disposed inside of the reforming catalyst and comprising a plurality of nozzles to direct flames at the reforming catalyst; a nozzle covering element to selectively cover a portion of each of the nozzles; a combustion fuel supply valve to change the amount of a combustion fuel that is supplied to the burner; and a controller that controls the nozzle covering units and the combustion supply valve. The method of controlling the reformer includes: moving the nozzle covering element to cover a decreasing portion of each of the nozzles in response to an increasing amount of the combustion fuel being supplied to the burner; and moving the nozzle covering element to cover a increasing portion of each of the nozzles in response to a decreasing amount of the combustion fuel supplied to the burner.
