Whenever a manufacturing behemoth like General Electric (GE 1.30%) builds a new product, companies in that space should become awfully nervous. So when GE announced that it had achieved a breakthrough in fuel cell technology, investors might think that the days are numbered for smaller manufacturers such as Ballard Power Systems (BLDP -2.76%) and Plug Power (PLUG -1.25%). Fortunately for them, this isn't the case for the time being because of the type of fuel cell that General Electric is manufacturing. 

"Wait, there's more than one type of fuel cell?" You bet, and the end use can play a huge role in what it is capable of. Tune into the video below to find out the difference between General Electric's new fuel cell design and that designed by Ballard and used by Plug Power, why they won't compete against each other.
