Hydrogen cell cars are cars that use hydrogen as a fuel source. Unlike other “environmental cars” like hybrids (which are a combination of batteries and a gasoline fueled engine) hydrogen fueled cars offer zero emissions. The only bye product of the car is water. By having zero emissions, hydrogen cell cars are considered one of the possible alternative fuels of the future, but they are already here. In 2005 Honda leased the first commercial hydrogen car to a family in Redondo Beach, California. Being in the public market is an important step into hydrogen cell cars becoming more common on the road but there are two main problems that need to be overcome first. One is the cost of hydrogen cars and the other problem is that there is no sizable infrastructure laid out yet (fuel stations, refineries for producing hydrogen, and the transportation of hydrogen). At the moment, the cost for a hydrogen car is quite expensive with a Shelby Cobra costing $149,000. Hydrogen fuel is also expensive; at the moment hydrogen cells can cost as much as one to twenty dollars a kilo. Also, there is not a sizable infrastructure in place yet. At the moment California has the most at 13 (as of 2004), but plan to have around 170 by 2010.
