How Hydrogen Cars Work is an article that will get into the basics of how exactly a hydrogen powered car works.

How Hydrogen Cars Work

A Car That Runs on Water? No Longer Science Fiction!

With gas now in some places in the US over $5 a gallon, and even higher in other locations in the world, a gasoline-free car is now becoming a holy grail for car manufacturers. Such a car has been invented and may be available at a local car lot soon. Hydrogen vehicles are now being used around the world, emitting instead of noxious carbon dioxide harmless water vapour.

Hydrogen vehicles—anything from scooters to airplanes—are vehicles that run on some sort of hydrogen fuel. Most hydrogen vehicles run on fuel cells, where hydrogen atoms are split and re-combined with oxygen, creating electricity to run the motor—not to mention environmentally-harmless water. Other hydrogen vehicles use standard, run-of-the-mill internal combustion engines, using a form of liquid hydrogen (either extremely pressurized or cooled) instead of gasoline.

Hydrogen has been powering life on Earth since the beginning of history. Our sun is nearly 75% hydrogen. Humans began using hydrogen to power electric motors in the early 1800s and Germany created the first hydrogen vehicle in the 1950s.

Hydrogen fuel cells work by splitting and recombining atoms inside the cell’s membranes and casings, allowing them to bond and unbond on a molecular level, which creates electricity.

However, hydrogen fuel cell cars have to get their hydrogen from somewhere, and energy is needed to “create” the hydrogen. While this energy can be made from “green” (or renewable) resources, it can also be made by not-so-green sources, such as coal burning, the burning of natural gas, or as a microbial waste product of decomposition.

Once the hydrogen is separated from other molecules in the water, it is chilled to a temperature of -253 C (-423 F) so it can be stored as a liquid and loaded into the hydrogen fuel station. It is pumped into the hydrogen car’s tank just like gasoline, and there it sits until the fuel cell needs a replenishment. The chilled liquid hydrogen enters the fuel cell, where the single proton and electron pair of the atom is split. Protons are sent one way; electrons are collected by the fuel cell to power the electric motor. Extra electrons are fused again to the proton, along with an oxygen atom, creating a water molecule—which simply exits out the exhaust pipe.

Today, major car manufacturers such as BMW and Mazda are experimenting with the hydrogen internal combustion engine, while Daimler-Chrysler, General Motors and Hyundai are focusing on fuel cells. A few companies, such as Ford, are researching both methods. Most of the hydrogen-powered vehicles are available now in Europe and Japan. BMW and Honda plan on releasing models to the general public in 2008.

If you're not in the market for a new car, you can try converting your current rig to hydrogen. Kits are available online to help your vehicle’s internal combustion engine use hydrogen to run. As hydrogen fuel stations become more prevalent, converting your current vehicle to run on hydrogen may be the most cost-effective method of running around town since running.

GM Hydrogen Car (NEW!) - There is a GM hydrogen car called the Sequel that is tantalizingly close to full scale production for the many people (im)patiently waiting for a hydrogen powered vehicle. Environmentalists, technocrats, and people who are simply tired of gasoline prices skyrocketing with no end in sight may yet find their dreams of clean, affordable driving answered....

BMW Hydrogen Car - Question: How is BMW’s new Hydrogen 7 like the hard-earned cash flocks of people are spending to own one? Answer: It’s green! That’s right, BMW’s new luxury performance sedan is being touted as a mean, green, environment-loving machine capable of running on liquid hydrogen while discharging almost nothing but water vapor. And it will do all this while most cars still spout nauseating, ozone killing carbon dioxide. But before you grab for your wallet or sign that lease, be warned: this glimpse into an “eco-friendly” future is a mixed bag filled with both innovative wonders and glaring issues...

Buying a Car ; New vs Nearly New vs Used - Budget conscious car shoppers must weigh the good with the bad when buying a new vehicle as opposed to one that is nearly new or used. In the past, it was not smart to buy a new car because of the financing costs and the taxes added to the listed price. On top of that, a car depreciates in value rapidly, unlike a new home, generally 50 percent over the first three years. Furthermore, penny-pinching car buyers could not fathom buying a new vehicle in years past because .....

Fuel Efficiency - Gas prices are down, some argue because it’s an election year, but odds are they will be on the rise again soon. Consumers will be challenged once again to overcome their fuel-pump fears. The inflation of gas prices in recent years have made drivers look at alternative means of transportation, or forsaking a gas-guzzling sports utility vehicle for a small economy car. Hydrogen-powered cars are steadily becoming more of a reality. Mass-production of such vehicles is now a probability, within a decade. But what are drivers to do between now and whenever their fuel-pump fears can finally subside? The answer: Get serious about improving fuel efficiency in their existing vehicles. Drivers can save money driving what they own now in ways that most have overlooked.....

Hydrogen car conversion - Hydrogen-powered cars are likely a decade away from mass production, but can the consumer really wait that long, especially in light of record gas-price increases in 2005? In what has become the “Now Generation,” scientists and consumers alike are anxious to experience this very moment the opportunities hydrogen-powered vehicles have to offer. They can not wait to eliminate the dependability on gasoline. They hunger to use a fuel cell to run an electric motor, leaving the nightmares of spending more than $3 a gallon of gasoline behind....

Hydrogen car manufacturers and prices - Hydrogen fuel cell vehicles are now available, with many automobile manufacturers revealing models this year in their showrooms, but affordable styles are still about five to 10 years away. General Motors, which currently has a fleet of six HydroGen3 vehicles in Washington, D.C., announced in October that by 2010 it will widely develop economically viable models of the hydrogen-powered vehicle. The largest automobile manufacture is already in the process of building a New York fleet of 40 cars under the U.S. Department of Energy's Infrastructure Demonstration and Validation Project. General Motors puts a price tag of...

Alternative Fuel Vehicles - Motor vehicles contribute significantly to greenhouse gases but nevertheless the rise and rise of petrol, diesel and kerosene vehicles continues at an alarming rate. Not only do vehicles contribute net carbon gases, mainly CO and CO2, into the atmosphere which contribute to global warming and climate change but the products of combustion also produce additional local pollution. Our apparently illogical passion to burn fossil fuels this way stems from three main factors: consumer demand, supplier economics and national interests. These driving forces are fundamentally underpinned by the fact that petroleum products (from oil and gas) are, for the time being, readily available and cheap at source. Further, up to now, there has been little in the way of competitive alternatives...

Buy Hydrogen Car - Hydrogen-powered cars are catching on with major automobile manufacturers, but will attempts to gain uneducated consumers in this new technology dissolve into thin air?. It appears this new method of powering cars is here to stay, although it looks to be a slow process for it to take the whole world by storm. Hydrogen cars are gaining support from federal and state governments in the United States because of the drastic increase in gas prices, and the growing threat to our environment from emissions released by fossil fuel. ...
