Hydrogens Cars

general presentation and usefulness:
The hydrogen car is a vehicle who uses hydrogen as fuel, cells in the vehicle are 
filled with hydrogen, this type of vehicle can be very useful in the future because
the hydrogen is one of the most common gas in the universe and it renewable

 how works an hydrogen fuel cell:

the fuel cell receive dihydrogen and it  goes in the anode,after the dihydrogen atom is separate in electrons and H+ ions.the ions pass through the electrolyte and the electrons pass through a conductive material and generate electric current, this current will be used by the cars to move,the h+ ion and the electron go after in the cathode,they combine together to return to a dihydrogen atom.This atom combine with  air molecules to turn into  water.

how work  an hydrogen car in general:
