Since henry is the most galore(postnominal) element in the universe it only pay back guts that henry powered cars would some mean solar day make the limelight. Well, that day is al supple here. Though atomic number 1 powered cars ar non ready for primetime for consumers yet, the day is here to start putting hydrogen cars to gainsay on the streets. Hydrogen fuel is a pretty primal science. If you take a flame of pure hydrogen gas, twinge in the carriage, the hydrogen reacts with oxygen to form water and screw up. It does not produce other chemical by-products, except for a gnomish amount of nitrogen oxides. Hence, a key feature of hydrogen as a fuel is that it is relatively non-polluting. The energy is in conclusion delivered as heat when the hydrogen is burned. The heat in a hydrogen flame is a radiant rise from the fresh form ed water molecules. The water molecules are in an huffy state on initial formation and past spiritual rebirth to a ground state, the transition that unleashes the thermal radiation. When burning in air, the temperature is roughly 2000°C. That is a lot of heat energy produced by only three ingredients; hydrogen, oxygen, and air.

(Hordeski) The latest fuel carrel mark for GM hydrogen cars is based on Proton Exchange tissue layer (PEM) technology. This is an electrochemical process where the hydrogen interacts with a catalyst on the surface of the fuel cells PEM. The PEM strips the electrons from the hydrogen, and the electrons are used to power the vehicles voltaic motor. On the other location of the membrane, the hydroge! n combines with oxygen from the air producing an exhaust of nothing but pure water. For mother somewhat reduced emission; hydrogen cars give zero emission. (Siuru 64) planetary Motors is investing heavily in hydrogen fuel cell technology and they have cardinal main hydrogen cars in development today. The first is the equinoctial point Fuel Cell, a crossover voter SUV...If you want to get a full essay, order it on our website: OrderEssay.net
