Why don’t the auto makers just make a car that runs off of pure oxygen? Wouldn’t it be cheaper to make a car that takes in air form outside. Separates the nitrogen and compresses the oxygen using that for the combustion instead of putting thousands of dollars in to hydrogen fuel cell technology and electric cars? all it would require are storage tanks and a highly efficient air compressor as well as a slightly modified engine.
fuel cell technology
Do fuel cells hold a formidable advantage over liquid hydrogen kept at harsh below freezing temperatures ?
Fuel cell technology being developed by several automakers, namely Honda and Chevy, is a non-combustion form of energy unlike liquid hydrogen which essentially uses the same engine structure as conventional cars. This require liquid hydrogen to be kept in the vehicle at 420 degrees below zero which is costly. In fuel cells, hydrogen based cells are kept on stacks. A hydrogen – oxygen reaction creates electricity that powers the car. The fuel cells are refilled with the hydrogen chemical.
