It does, but in the context of this whole thread H2 is being seen as a way to deliver the energy for these powerful new motors but the fact is the power does not come from nowhere and an H2FC cannot deliver the current needed to generate the levels of power that are required and you needs batteries. Any vehicle where weight is a factor is going to have to choose, H2FC for quick refuelling or batteries for high power. In racing, I think we are seeing with Formula E that batteries are the best choice and they deal with refuelling by switching out the car for an identical model that is fully charged. Racing will cope with a switch to electric motors and batteries just fine, it is unlikely to be hydrogen because the weight of the combined H2FC and batteries really make it uncompetitive if the motor power has to be restricted, and the idea of handling hydrogen in a pit stop just gives me the willies. Formula E is great fun to watch to be honest and the challenges of handling energy make for a fantastic competitive field.
