TPO-09 - Integrated Writing Task Car manufacturers and governments have been eagerly seeking a replacement for the automobile's main source of power, the internal-combustion engine. By far the most promising alternative source of energy for cars is the hy

The article explains why hydrogen-based-fuel-cells are better than the internal combustion engine, used to produce energy in the car. However, the speaker refutes the author's claims.

Firstly, the article says hydrogen-based-fuel-cells rely on hydrogen, which is abundant, unlike the internal combustion engines which rely on petroleum, a finite resource. But the speaker disagrees saying that hydrogen production is difficult and impractical though it is abundant. Fuel-cell engines require hydrogen as an artificial substance in its pure liquified form. This is difficult and in addition, it requires sophisticated laborative cooling technology.

Next, the author claims hydrogen-based-fuel-cells are environment-friendly because water is the only byproduct, which is not harmful unlike the byproduct of the internal combustion engine, carbon dioxide. However, the speaker says hydrogen producing factories are more harmful than the cars that operate on fuel cells because the production of hydrogen needs oil and coal to burn which generates carbon dioxide thus harming the environment.

Finally, the author claims that hydrogen-based-fuel-cells are economic since they are more efficient than the internal combustion engine. The speaker, in contrast, contends the component platinum, used for these fuel cell is expensive and rare. Furthermore, only platinum can be used to initiate a chemical reaction that produces energy.

Because of the above reasons, the speaker refutes the author claims that hydrogen-based fuel cells are economic, environment-friendly and easily available.
