Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a highly durable desulfurization system for a fuel cell capable of maintaining the desired desulfurization performance even when hydrocarbon-based fuel containing poisoning substance of a desulfurization agent is supplied, and to provide a hydrogen manufacturing system, a fuel cell system, and a sulfurization method of the hydrocarbon-based fuel.SOLUTION: The desulfurization system for the fuel cell includes a desulfurization part for removing a sulfur compound from the hydrocarbon-based fuel containing the sulfur compound and circulated therethrough. The desulfurization part is composed of a plurality of zeolites each supporting active metal in different concentration and includes the desulfurization agent in which the plurality of the zeolites are arranged in the order from the zeolites of high active metal concentration to the zeolites of low active metal concentration from the upstream side in the circulation direction of the hydrocarbon-based fuel toward the downstream side thereof.
