| Research Abstract |
Decomposition of a perfluorinated ion-exchange membrane used for fuel cells, in subcritical water was investigated. Although the membrane showed little decomposition in pure subcritical water, the addition of several zerovalent metals to the reaction system accelerated the membrane decomposition to fluoride ions, and the acceleration increased in the order Al<no metal<Zn<Cu<<Fe. When the membrane and iron powder were heated in subcritical water at 350 oC for 17 h, 73.2% of the fluorine content in the initial membrane was successfully transformed to fluoride ions.
