The speaker, on the topic of the bright future of the replacement of hydrogen-based fuel-cell engine, challenges the validity of the reading material, providing the opposite evidence concerning the influence on the fuel-cell’s available sources, low pollution and economically competitive power.

First, the speaker points out that it is highly doubted that hydrogen-based fuel can easily be derived from various plentiful sources. As opposed to the passage this kind of energy is difficult to produce and store for it must be existed in pure liquid state to produce the fuel though widely sources. Meanwhile, the sophisticated technique, to make this environment, asks for 253 degree centigrade below zero, which makes it hardly practical to be used. From the case, the lecture has effectively railed against the passage.

Secondly, hydrogen-based fuel may also give rise to much pollution. Despite of the assumption of the passage that the only product of the fuel-cell engine is water, the speaker claims that to produce this fuel calls for a lot of energy based on the burning of coal and oil, which stills cause lots of pollution through the process to get the fuel. This is another part the speaker questions the passage.

Thirdly, fuel-cell engine may not be efficient in economic as it is supposed. According to the speaker, though hydrogen may be cheap and competitive enough compared with petroleum, the chemical reaction, which hydrogen is involved in to produce the electricity for the automobile, requires a very expensive metal to take part in, while other cheap metal can not stimulate the reaction. Such information has refuted the passage.
