At an average requirement of 30g platinum per vehicle for an 85kW electric engine, using today’s technology, the amount of platinum used for conventional drives in cars would be sufficient for only approx. 3 million fuel cell vehicles.

Hydrogen-fuel-cell technology, however, relies on platinum, which can withstand higher temperatures than other metals. A fuel cell needs platinum for the catalyst that separates hydrogen into protons and electrons, which then generate the electrical current, making it an alternative to battery-powered vehicles.

In a fuel cell, platinum is used two ways — to convert hydrogen into protons and electrons, and to break oxygen bonds and eventually form water. The core-shell nanoparticles on their own still could not handle a large influx of oxygen when the fuel cell needs to crank up the electric current.

Platinum jewelry is more expensive than gold… It’s a well-known fact. Aside from assuming that platinum is a superior metal, have you wondered exactly why platinum gets the higher ticket price in the jewelry industry? Currently, gold costs around $1,300 per ounce, while the going price for platinum is $850 per ounce.

Most pawnshops, if not all, only accept gold jewelry, but others can also accept silver, platinum, and other precious metals. These should be in good condition: no damage, no chipped stones, no missing pieces. They assess the price according to the weight and size, if it’s in mint condition or if it has damages.

Platinum cannot be considered an investment If you are planning to buy platinum jewelry as an investment, think again. The consumption of platinum, though on the rise, still isn’t as popular as gold and diamonds in the country.

Approximately 88 tons of platinum are used to make jewelry every year compared to 2,700 tons of gold. Because of its rarity, platinum is valuable and will hold its value as the years pass.
