using the fuel-cell engine to power cars instead of the internal-combustion engine

using the fuel-cell engine to power cars instead of the internal-combustion engine kYjyW
The material discusses the usage of hydrogen-based-fuel-cell engine to power cars instead of internal-combustion engine. While the reading states that using fuel-cell engines have several advantages, the listening mentions that the reading is correct in pointing out the problems related to using petroleum, but the professor says that the author is very optimistic. First, the writer posits that hydrogen can not be easily declined and it could be brought from many sources, such as water and natural gas. On the other hand, the lecturer challneges this and states that hydrogen is not easily available. the professor mentions that people could not use hydrogen directly from water, but it should go through complicated process. The listening adds that hydrogen in a pure liquid state is high artificial substance. The speaker explains that it could be produced in a very cool temperature, which is very hard to attain. Second, The author claims that using fuel-cell engine could solve the world's pollution problems. On the contrary, the lecturer opposes this and states that using hydrogen to power cars is not a realistic way to solve pollution problems. The professor explains that producing hydrogen from water or natural gas needs to burn coals or oil and that could produce lots of pollution. Third, the reading mentions that using fuel-cell engine is cost-effective. The speaker refutes this and states that it is not necessary for hydrogen to be less costive. The professor explains that the maufacture of hydrogen costs lot money becasue the engine should have platinum metal, which is very expensive. The lecturer adds that without this metal the hydrogen could not do reaction and produce electricity.
