The reading and listening materials have a debate on the availability to replace the internal-combustion engine with the fuel-cell engine. The writer believes that the fuel-cell engine has three main advantages over the internal-combustion engines, which are all contradicted by the following lecture.
Firstly, the writer claims that the renewable hydrogen required by fuel-cell engines is more available and sustainable than the finite gasoline burned by the internal-combustion engines. However, the speaker casts doubt on it by saying that the hydrogen is not easily available since water cannot be directly used to create it. To begin with, people have to obtain water in pure liquid state which is a kind of highly artificial substance. Besides, the hydrogen can only be produced under extreme cold temperature, minus 253 Celsius. As a result, the easy access to hydrogen is not practical.
Secondly, the author argues that, compared with the internal-combustion engine which releases harmful carbon-dioxide, hydrogen-based fuel cells can better solve the problems of environmental pollution, while the lecture views this issue from an opposite angle. According to the professor, even though the fuel-cell engine will not discharge exhaust gas during the utilization, the process of creating hydrogen will cause much pollution. The purification process needs numerous energy required from burning coal or oil that gives rise to the pollution of factories.
Thirdly, the passage states that it is more economical to operate a fuel-cell engine than an internal-combustion engine. On the contrary, in accordance with the professor, this claim does not hold water. It is because the speaker did not consider the cost to manufacture the fuel-cell engine which is made of platinum. Without platinum, the engine is not able to produce chemical reaction and power the automobile. What’s more, people’s attempt to replace platinum with cheap elements is not successful.
To sum up, the author’s statements are totally refuted by the professor. Accordingly, whether the fuel-cell engine is better than the internal-combustion engine is still under heated debate.
