<P>PROBLEM TO BE SOLVED: To provide a method and a apparatus of restoring fuel cell catalyst in which a degraded catalyst layer of a fuel cell is restored in a simple manner. <P>SOLUTION: This method of restoring a fuel cell catalyst includes a first step of adhering Pt ions onto a carbon black carrier on the side of degraded electrode, and a second step of providing hydrogen and gas containing hydrogen to an electrode opposite to the degraded electrode and reducing the Pt ions adhered to the carbon black carrier to Pt by applying a voltage between both electrodes. In the restoring apparatus, a water container 40, a Pt compound aqueous solution container 42 and an acid aqueous solution container 44 are coupled to the fuel cell 30 via a liquid supply passage 32, and thus the catalyst layer on the side of the degraded electrode receives supplies from the respective containers. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
