Hydrogen engines.
Fuel cells operate by combining hydrogen and oxygen without actual combustion as in gasoline engines. A catalyst separates the electrons and protons to combine the elements. (Some versions of fuel cells are high-temperature only.) Hydrogen gas
Internal combustion gasoline, propane, or diesel engines. Electric motors. Steam engines, fuel cell engines are examples of energy sources.
Yes, hydrogen is transferred into the power to move the car either by fuel cell (resulting in electricity) or a traditional ICE (Internal Combustion Engine). Either way, the end product is water vapor.
Fuel cells are basically a storage device for energy. In the cars on the road today they are gasoline tanks. In hybrid cars, they are gasoline tanks and batterys. In GM's Hydrogen car, the fuel cell is the Hydrogen tank.
No you cannot. Gasoline is a liquid; and the other is a gas. However you could make an engine or convert an engines fuel system which would run on methane ( f-rts ) compressed in a fuel cell. Besides, why do you want to?
Volvo has a concept car, the C30, which is a plug-in electric vehicle. The range is 94 miles. Volvo is researching adding a fuel cell which would extend the range another 155 miles. To overcome the lack of hydrogen fuel availability, Volvo is working on a reformer that will extract hydrogen from gasoline. This seems counterproductive at first glance. The process has an 85 percent efficiency rate and eliminates the need for hydrogen fuel stations.
Generally, a Hydrogen powered car runs by using hydrogen and oxygen to create electricity in a fuel cell, which is then used to power an electric traction motor that runs the car. Direct ignition-engines are more difficult and dangerous to 'run'.
Hydrogen can be burnt with oxygen and the formation of the chemical bonds between the atoms releases energy as heat. Free hydrogen is normally manufactured by electrolysis from water, and this requires energy to separate the hydrogen-oxygen bonds, and it is this energy that is released when the chemical bonds are re-formed by combustion.
A hydrogen combustion engine is like the engine in your car. Hydrogen and oxygen enter a combustion chamber, ignite, and form a ball of hot vapour (steam) which moves a piston that rotates a crankshaft. Alternately a hydrogen combustion engine could be a rocket or jet engine where the burning fuel exhausts the combustion chamber as vapour (steam again) and impacts a forward motion to the engine by the mass discharge. A fuel hydrogen cell is more like a battery. Hydrogen and oxygen react in a catalyst matrix that allows the process to continue at a fixed rate. Like most chemical reactions this involves the movement of electrons to create positive and negative reactant ions. The flow of electrons is conducted to an electrical system as power. Water is still the byproduct.
Water is the benefit of a hydrogen fuel cell ;)
It depends how far you want to go, how fast, and how big your car is! But when you ask a vague question you get a vague answer... a lot. The energy density of hydrogen is much lower than gasoline, even when it is highly compressed.
