Last summer we first saw one of General Motors new fifth-generation fuel cell stacks on display at a powertrain technology event. It was being shown next to the comparable hardware from one of the Project Driveway fuel cell Chevy Equinoxes and the difference in size was startling. The stack is part of what GM refers to as the second-generation system which includes all the elements necessary to implement it in a vehicle. The system consists of the stack, the fuel storage, electronics and all the ancillary components.
The new system is less than half the size of the Equinox system and uses only one-third as much platinum while producing more power. The new stacks are now being tested in GM's fuel cell labs in Honeoye Falls, NY with the goal of selling production vehicles by 2015. Manufacturing engineers like Lucy Wilke are focused on developing the processes necessary to produce fuel cells in volume at an affordable price. Check out the video after the jump.
