Can you help me come up with a thesis
The impact of hydrogen fuel cells comes into their use in electric vehicles. The hydrogen fuel cell operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other. The hydrogen reacts to a catalyst on the electrode anode that converts the hydrogen gas into negatively charged electrons (e-) and positively charged ions (H+). The electrons flow out of the cell to be used as electrical energy. The hydrogen ions move through the electrolyte membrane to the cathode electrode where they combine with oxygen and the electrons to produce water. Theoretically, unlike batteries, fuel cells never run out. But, HFCs produce water as a byproduct, and are thus considered neutral to the environment, even though technically they may be adding water vapor. What they are *not* adding are any volatile organic compounds, nitric or sulfuric gases, exhaust particulates or any of the other things that come out the end of your car when you're using gasoline or diesel. So your thesis might be that using HFCs benefits the environment by reducing the emission of greenhouse gases that (in theory) heat up the atmosphere. So that would be not a solution but at least a big help to the climate, by not punching it in the face any further. Over time, it would balance itself out again. The problem with HFCs is that (a) You need a hydrogen source to build them (b) It's a rather messy process to make the HFCs in the first place (c) as above, the water and water vapor. One of those good and bad situations at the same time.
Just think for a minute - what would the climate-damaging emissions be, if cars and trains etc were propelled by hydrogen, compared to burning fossil fuels like coal and oil? Better or worse? How much better? Do a little research, say, using wikipedia
