GM develops much better hydrogen fuel cell

The North American automaker, General Motors, has developed a new hydrogen fuel cell technology. This new fuel cell technology permits smaller sized units to be made that also bring significant weight savings. Also, this new fuel cell technology permits the creation of hydrogen fuel cells that have a cheaper production cost and have increased efficiency. In a picture below you can see the new fifth generation fuel cell of 93 kW put next to a fourth generation fuel cell that has the same 93 kW. The fourth generation 93 kW hydrogen fuel cell is currently used in the GM Equinox SUV. From what you can see in the pictures below, the new fifth generation hydrogen fuel cell made by General Motors seems like a huge improvement. The fact that the GM`s new hydrogen fuel cell is a lot smaller and has increased efficiency is great, but being cynical, everything is about the money. The fact that the new hydrogen fuel cell has a lower production cost is the most important fact for GM. To be more precise, the engineers working for General Motors have managed to reduce the amount of platinum used by more than 50%, from 80 grams to 30 grams of platinum. The American automaker aims to lower the use of the precious metal further with the sixth generation of their hydrogen fuel cell, aiming to reach around 10 grams of platinum per fuel cell when the sixth generation is completely developed. Thanks to the lower size of a hydrogen fuel cell, the cost per fuel cell stack will surely go down a lot and the production will rise to 10.000 units until 2015 hopefully. The fifth generation of GM`s fuel cell has a life expectancy of 190.000 kilometers, a figure that is a lot higher compared to the life expectancy of the current fourth generation of the hydrogen fuel cell. This is a huge step forward done by General Motors and we expect to see more of the same in the future.
