KT asked:


will a fuel cell car (from frys) (toy car that runs on hydrogen) go faster with salt water in it than regular water? this is for science fair…..tell me if you know how to make it go faster with salt water ..thanks

   Let’s presume that with either type of water, the fuel cell puts out enough electricity to run the car’s electric motor. The electric motor will run a car at a certain speed due to the gear ratios. That’s as fast as it can go. To make it go faster, you’ll need a motor with more power/torque and a fuel cell that can provide the necessary power.

   Let’s assume that the electric motor will respond to more current than just regular water will produce. You need a catalyst to speed up the separation of water. Try adding a little baking soda to the water mixture. I believe it should speed it up a bit. Make sure you keep the anode and cathode clean of the sludge that forms.

   Hope this helped.
