<P>PROBLEM TO BE SOLVED: To provide a highly durable desulfurization system for a fuel cell capable of maintaining the desired desulfurization performance for a longer period, and to provide a hydrogen manufacturing system for the fuel cell, a fuel cell system, and a desulfurization method of the hydrocarbon-based fuel. <P>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 constituted of a plurality of porous desulfurization agents, each of which contains a porous body and has different pore size, and has desulfurization agents in which the plurality of the porous desulfurization agents, each of which has the different pore size, are arranged in the order from the porous desulfurization agents of small pore sizes to the porous desulfurization agents of large pore sizes from upstream side in the circulation direction of the hydrocarbon-based fuel toward the downstream side thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT |
