<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a metal ion-exchange zeolite suitable to be used for an adsorbent for removing a sulfur compound capable of efficiently removing the sulfur compound from a hydrocarbon fuel or a dimethyl ether fuel to a low content even at room temperature, the adsorbent containing the metal ion-exchange zeolite for removing the sulfur compound, a method for efficiently manufacturing hydrogen usable for a fuel cell from the hydrocarbon fuel or the dimethyl ether fuel desulfurized by the adsorbent and a fuel cell system using the hydrogen. <P>SOLUTION: The method for manufacturing the metal ion-exchange zeolite comprises carrying out metal ion-exchange of a type Y zeolite containing sodium of 0.5-5 mass% by using a solution which desirably contains metal ammine complex ions in order to cause the zeolite to carry the resulting metal. The adsorbent for removing the sulfur compound contains the metal ion-exchange zeolite. Furthermore, the hydrogen usable for the fuel cell is manufactured using the hydrocarbon fuel or the dimethyl ether fuel desulfurized by using the adsorbent, and the resulting hydrogen is used for the fuel cell system. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
