In terms of whether fuel-cell engines will probably soon replace internal-combustion engines, the reading and listening are contradictory to each other.
First, the writer makes the point that hydrogen is a better fuel source than oil because it is infinite. However, the speaker demonstrates a different idea that hydrogen is technologically difficult to produce and store. For example, the liquid state of hydrogen should be kept at an extremely low temperature.
Second, contrary to the belief in the reading passage that hydrogen-based fuel cells will solve pollution problems, the lecturer says that although the hydrogen powered cars will not pollute, the burning of coals and oils that produce the hydrogen will make pollution to the environment. .
Finally, the author states that fuel-cell engines are cheaper than internal-combustion engines. In contrast, the speaker refutes that fuel-cell engines are expensive, because they are made by a kind of precious metal. There are no other cheaper materials that can replace this metal.
