What is the hydrogen car?

Answer 1

A hydrogen car is a car that burns hydrogen gas instead of gasoline, the cars are pretty normal, instead of a gas tank they have a hydrogen container, made of composite material (steel gets brittle at the low temperatures which hydrogen is stored). The hydrogen car is filled up at a hydrogen station with liquid hydrogen, from the tank, a pipe routes liquid hydrogen to a set of valves and regulators which lower the pressure in stages and let the hydrogen into the intake manifold, the system works somewhat like the natural gas or lpg vehicles. For now these cars are expensive, hydrogen is not easy to get, they have poor range, and are thermodynamically inefficient. In other words, it takes too much energy to make hydrogen, store it, transport it, and as an energy carrier is not as good as a fossil fuel. Good thing is that these cars do not pollute, their exhaust is water. NOTE: Do not confuse these cars with a fuel cell car, those use hydrogen but are electric vehicles that use hydrogen to generate electricity with a very expensive electrochemical device called a fuel cell. Do not confuse a fuel cell with a Hydroxy cell, this si a device that operates on electrolysis to separate hysdrogen and oxygen in water and feed it into an IC engine WITH gasoline, these devices are used as combustion enhancers and their efectiveness is being tested, some peope report great results, others report no gain at all.
