5. Conclusion

In this document, we have reviewed the main applications, which are extremely varied and touch on almost every sector. It should also be noted that fluctuations in the price of precious metals have had little impact on certain industrial applications, such as catalytic converters. In the field of fuel cells, platinum group metals have an operating temperature below 100°C, which is a real advantage.

• Given the scarcity of these metals, it is vital to recycle them , an operation made all the more difficult by the fact that their melting point is often in excess of 2,000°C. Recycling methods are becoming increasingly complex, and the...
