<P>PROBLEM TO BE SOLVED: To recover catalytic metals without performing a process of incineration of generating environmental pollution gases from fuel cell elements containing the catalytic metals and a fluororesin. <P>SOLUTION: The method for recovering the catalytic metals includes: a first process (step S100) of preparing the fuel cell elements containing the catalytic metals and the fluororesin; a second process (step S120) of treating (step S110) the fuel cell elements with a supercritical fluid and of decomposing the fluororesin in the supercritical fluid; and a third process (step S130) of obtaining a solid component containing the catalytic metals which contain the catalytic metals as a residue of the fuel cell elements passing through the second process. <P>COPYRIGHT: (C)2011,JPO&INPIT |
