In the given sets of materials, the main topic has centered on whether Hydrogen fuel-cell engines have different redeeming features or not. While the author has focused on the positive points for using this fuel as the source of car's power, the speaker in the follow-up audio material cast doubts on those points by providing justifications.
The first point mentioned in the article is that contrary to the previous unrenewable source of energy, Hydrogen is accessible easily. However, this was questioned by the lecturer as she stated that extracting pure, liquid form of Hydrogen for fuel-cell have required hi-tech structures to make it liquid.
Moreover, according to the essay, to tackle the air-pollution crisis, fuel-cell engine seemed proper because of its safe by-product, known as water. Nonetheless, the speaker discussed that most purification factories needed to change Hydrogen construction in order to make it ready for vast use. In fact, these factories with a high rate of fossil-fuel emission would become one of air polluting source.
Last but not least, the writer has mentioned that one of the most significant advantages of using fuel-cell automobile is its cost-saving function as it uses less amount of power source. Conversely, according to the professor, the container of Hydrogen should make by palatine to facilitate its chemical reaction to combust. Hence, it would be expensive.
