Hydrogen Fuel Cells
Problem Statement
The new car on the market is a hybrid one. Hybrid cars are powered not only by conventional fuel, fossil fuel, but also by electricity which it generates during everyday driving. These cars are very efficient now, but in the future when nearly all the fossil fuels have been burned up and it is too expensive to use it in the large scale economy. I believe hydrogen fuel cell powered cars will take over the automobile market for several reasons. First, hydrogen is one of the most abundant resources on the planet and can be extracted anywhere on the planet unlike fossil fuels. Second, power, hydrogen fuel cells provide more than enough power to drive any type of automobile. Third, size, a hydrogen fuel cell motor is far smaller than a typical combustion engine which allows designers to put any type of body style on the same engine. Fourth, unlike todays motors, hydrogen fuel cells are 100% ecologically safe. Fifth, hydrogen fuel cell cars are catching on fast in the automobile market around the world.
