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 hydrogen-based fuel-cell engine, which uses hydrogen to create electricity that, in turn, powers the car. Fuel-cell engines have several advantages over internal-combustion engines and will probably soon replace them.
One of the main problems with the internal-combustion engine is that it relies on petroleum, either in the form of gasoline or diesel fuel. Petroleum is a finite resource; someday, we will run out of oil. The hydrogen needed for fuel-cell engines cannot easily be depleted. Hydrogen can be derived from various plentiful sources, including natural gas and even water. The fact that fuel-cell engines utilize easily available, renewable resources makes them particularly attractive.
Second, hydrogen-based fuel cells are attractive because they will solve many of the world's pollution problems. An unavoidable by-product of burning oil is carbon dioxide, and carbon dioxide harms the environment. On the other hand, the only byproduct of fuel-cell engines is water.
Third, fuel-cell engines will soon be economically competitive because people will spend less money to operate a fuel-cell engine than they will to operate an internal-combustion engine. This is true for one simple reason: a fuel-cell automobile is nearly twice as efficient in using its fuel as an automobile powered by an internal-combustion engine is. In other words, the fuel-cell powered car requires only half the fuel energy that the internal-combustion powered car does to go the same distance.
The article and the lecturer are both about diferenciation between fuel cell engine and internal combustion engine. The author of reading feels that fuel cell engines have several advantages over internal combustion engines. The lecturer challenges the claims made by the author. The lecturer thinks fuel engines have disadvantges.
First of all, the author argues that hydrogen needed for fule cell engines. The article notes that hudrogen can be derived from various plentiful sources including natural gass and even water. This pint is challenged by the lecturer. He claims hydrogen is not easily available device as use pure liquid stage. Furthermore, he says that this stage very dificult to produce and not much practicaly do.
Secondly, the author suggest that hydrogen based fuel cells unavoid to produce carbon dioxside and this way is attactive for enveroment polution . The article notes that this fuel cell engines give water as by product. The lecturer rebuts this argument. He suggests that pure hydrogen liquid are not purify hundered present. He elobarates onthis by mentioning that hyderogen fuel cell engines is not solution for envernment polution by vehicles.
Finaly, the author states that fuel cell engine econmically competitive because people will spend less money to operate fuel cell engines. Moreover, fuel cell powered car requires only half the fuel engergy than the internal combustion powerded car doess to go the same distance. In contrast, the lecturer's position is that fuel cell engines have to use platinum. He notes that it is very expensive.
