According to an embodiment, a fuel cell system includes an anode supply circuit is configured for delivering an anode source fluid to anode components. The anode supply circuit includes a primary supply path, a desulfurizer situated along the primary supply path, and a pre-reformer downstream of the desulfurizer and upstream of the anode components. The pre-reformer converts a portion of anode source fluid into an anode reactant and yields a reformed source fluid that includes the anode reactant. A first feedback path carries anode exhaust fluid from the anode components such that at least some heat associated with the anode exhaust fluid facilitates the pre-reformer converting at least some anode source fluid into the anode reactant. A second feedback path carries at least a portion of the reformed source fluid to be mixed with the anode source fluid provided to the desulfurizer.
