The present invention provides a combustor for a fuel processor which integrates a burner and a catalyst. The burner is utilized to quickly heat the catalyst to a light-off temperature to prepare it for normal operation. The heated catalyst is then used to react anode exhaust with air or cathode exhaust under normal operation.
