In this article it is basically talking about how the scientists are making new and improved fuel-cells that are stronger than the other ones that we used before the scientists came up with the new fuel-cells. And the new ones are now not only more more stable but stronger to. Now, scientists at the DOE (U.S. Department of Energy) have made something that uses only a single layer of platinum and it makes it more harder to brake it and minimizes the risk of it tearing and wearing off.

Here are some things of the quotes from this article:
"Our studies of the structure and activity of this catalyst -- and comparisons with platinum-carbon catalysts currently in use -- illustrate that the palladium core 'protects' the fine layer of platinum surrounding the particles, enabling it to maintain reactivity for a much longer period of time," explained Brookhaven Lab chemist Radoslav Adzic, who leads the research team.

"This indicates the excellent durability of this electrocatalyst, especially when compared with simpler platinum-carbon catalysts, which lose nearly 70 percent of their reactivity after much shorter cycling times. This level of activity and stability indicates that this is a practical catalyst. It exceeds the goal set by DOE for 2010-2015 and it can be used for automotive applications," Adzic said.
