Gasoline (汽油) prices are getting higher and higher. The prices make it hard for drivers to afford the fuel. One group held a special event to display（展示）new kinds of cars .The new cars are different and they can run on many different kinds of fuels.
Some of these cars are called hybrids(混合动力). They can run on different kinds of fuels. One kind of them runs on a special fuel cell which is filled with a gas calledhydrogen.
The fuel cell cars are also better in another way. They give off no emissions（排放物）. They are very clean, and don't give off bad fumes when they are running.
One man who makes fuel cell cars is excited about the hydrogen fuel cell technology. He says we will never run out of the sources of the fuel, but we may run out of the oil. Once we use oil up, it will take millions of years for more oil to form. Since gasoline is made from oil, that could be a problem for companies that make traditional cars, and for drives. However, it won't be a problem for cars that run on fuel cells.
Buses that run on hydrogen fuel cell power are being tested on the road. They could become a common form of transportation in the near future
