So I got quite the bargain last week, picked up twelve “Hydrocar” science kits for under $20 total ($85 each at HorizonFuelCell’s store)!
Check out what they look like here:

It includes a plastic chassis for the car, a reversible fuel cell (also used for electrolysis), solar panel, battery pack, gas containers, and plastic tubing used for connecting everything. Each fuel cell outputs about 0.9V, and powers the small electric motor inside the car.
I plan to further investigate the efficiency of these fuel cells, attempt to find out what type of catalyst is used, and find some other applications (diy) for the fuel cells.
