How to recover high purity platinum from MEA using ultrasonic waves |
| abstract |
The present invention relates to a method for recovering platinum (Pt), in particular, by separating the platinum catalyst electrode and Nafion from the waste electrode assembly (MEA) of the fuel cell using an organic solvent, and then dispersing the platinum catalyst using ultrasonic waves. The present invention provides a method for recovering the total amount of platinum used in a fuel cell by increasing reactivity and selectively dissolving and reducing platinum in the platinum catalyst. |
