Hydrogen Cars

By Aden Kranz

Information on Hydrogen Cars Below! (what else?)

There are 2 types of hydrogen cars- combustion and electrical hydrogen cars. Combustion hydrogen cars work just like normal combustion-engined cars, but instead of using fossil fuels, which, when burned, produce various toxic gasses, use hydrogen. Unlike fossil fuels, when hydrogen is burned, it binds with oxygen atoms in the air to produce H2O in the form of water vapor.


Hydrogen itself is an element composed of a proton and an electron. It can be found in water, also known as H2O, which is made of 2 hydrogen atoms and an oxygen atom. Hydrogen has 1 valence electron and an energy level of 1. It can react in all 3 ways- it can give, receive, and share electrons. It's also extremely combustible!


In order to obtain hydrogen one must use device called an electrolyzer. An electrolyzer uses an electric current to split water into hydrogen and oxygen atoms, which are stored in different tanks. There are different types of electrolyzers, pacifically polymer electrolyte membrane (PEM), alkaline, and solid oxide electrolyzers, but they all use the concept explained above (literally in the last sentence, so the chances are that you remember it!).


The reasons why hydrogen cars are being developed are that they leave no carbon footprint, don't produce greenhouse gases (see top paragraph for details!), and that hydrogen fuel can be produced from water (I told you about that last paragraph!).


That's all for hydrogen cars! (I hope I didn't bore you to death.... But then again, if I did, you probably wouldn't be reading this sentence....)
