I haven’t made a hydrogen powered car yet, but there have been quite a few fuel cell powered vehicles:

A fuel cell is like a clever battery. It takes hydrogen and turns it into water in a controlled way. It takes all the energy released (and there is an awful lot!) and turns it into electricity. This is can then be used to make an electric motor work and then you have an electric vehicle.
My work is to make materials which can sort a mixture of gases. What I would like to find is a material which holds on to all the other gases in a mixture and leaves clean hydrogen. This can then be bottled, sold and used in fuel cells.
