Green Car 2 – Fuel Cell Vehicle

Park Jung Kyu, a researcher at Korea Industry Technology Institute



1. What is the difference between the fuel cell vehicle and electric vehicle?


Fuel Cell Electric Vehicle (FCEL) is different from Green Vehicles that uses hydrogen. The   way to produce electric energy for Fuel Cell Vehicle is different from electric vehicle. How the motive power is delivered is the same as the electric vehicle. Electric vehicle gets a supply of electric energy from outside by charging the battery, but Fuel Cell Vehicle does not charge the battery but produces electric energy on its own. It is easier to understand if you think Fuel Cell Vehicles have their individual power plants. Fuel Cell Vehicle has fuel cell system to produce electric energy on its own, and this is a component only for Fuel Cell Vehicles that cannot be found in any other cars.



2. How does Fuel Cell Vehicle produce power?


Now, let?s take a look at the individual power plant of Fuel Cell Vehicles. The fuel cell system produces electric energy by producing electrochemical reaction between hydrogen fuel and oxygen in the air. This electric energy is stored inside batteries or used as direct electric power. Because electric energy is produced by electrochemical reaction between hydrogen and oxygen and only emits water, the Fuel Cell Vehicle can be considered as pollution-free vehicle that contains no toxic substances, such as CO2, Sox, or NOx. But then hydrogen is a substance that is difficult to handle. It has high risk of explosion and is difficult to load massive hydrogen at once. This is why there are parts only for Fuel Cell Vehicles, called hydrogen storing system and fuel cell system. The hydrogen storing system is being developed rather actively for hydrogen to be stored and used more safely as fuel.



3. Can Fuel Cell Vehicle travel further than electric vehicle?


Yes. Fuel Cell Vehicles can travel more than 600km on a single charge. Isn?t it amazing compared to how electric vehicles travel 100~150km on average? Tussan ix FCEV, a Korean fuel electric car that was introduced in Renewable Energy Korea that was held in COEX in Seoul on October, 2011, is possible to travel 650km on a single charge. The traveling distance got much longer than 370km of existing Tussan diesel automobile, right? With this Fuel Cell Vehicle, we can make 2 trips from Seoul to Kangwon-Do on a single charge.



4. Then, is there enough hydrogen station?


There are only 200 hydrogen stations in the world right now and about 10 stations are located in our country. I believe more hydrogen stations will be established as the usage of hydrogen energy is becoming more diverse and research on Fuel Cell Vehicles is in the substantial stage. If we use Fuel Cell Vehicles right now, the hydrogen stations would be far from enough, right? The traveling distance of Fuel Cell Vehicles on a single charge is 600km but if we want to charge the energy more conveniently as gasoline/diesel cars, we need much more hydrogen stations.


But, would it be great to have a hydrogen station in our neighborhood? No. Generally, a gasoline/diesel station or LPG station is considered as an unpleasant facility. So, for a hydrogen station that requires more safety, it wouldn?t be easy to get land for stations because people will not be comfortable with the idea. Moreover, one hydrogen station requires 2 times greater construction costs than existing stations. Expanding of hydrogen stations would not be easy because of extensive difficulty of preparing the land as well as the expensive construction cost. I am certain that the factors mentioned above will gradually disappear as Green Cars replace gasoline/diesel vehicles and Fuel Cell Vehicles become generalized. Oh yeah, the charging time for hydrogen fuel is important, too. It would be very inconvenient if it takes too long to charge like electric vehicles. It takes about 20 minutes to charge hydrogen fuel right now but it is estimated that the charging time will be as short as 3 minutes in 2013.



5. How much is Fuel Cell Vehicle?


Fuel Cell Vehicles are very expensive because only a small quantity is produced as trial manufactured goods. One Fuel Cell Vehicle costs 1.5 billion won (?10 year model). Even 10 thousand cars are supplied in 2015; the cost is expected to be about 50 million won. It is very expensive compared to other gasoline/diesel cars today. Why are they so expensive?


There may be many reasons, but let?s talk about the platinum that is used in fuel cell system. Fuel Cell Vehicles use platinum as the electro catalyst of hydrogen and oxygen in order to produce electric energy. Platinum is the key material, but it is very expensive. Also, it?s the primary source of increased price of Fuel Cell Vehicles because the amount of reserves is very small. In addition, platinum is not produced in our country at all. This is the reason why many scientists are having difficulty in finding catalyst that can replace platinum.  



6. Then, is electric vehicle better than Fuel Cell Vehicle?


Just like the cost problem of Fuel Cell Vehicle, performance problems, such as short traveling distance, need to be resolved for electric vehicles. Researchers prefer to use electric vehicle for short distance and Fuel Cell Vehicle for long distance. We can get answers to these two questions by observing how technical development progresses. Now, lets introduce hybrid vehicles next.

    Interestingly, hydrogen fuel cell cars produces (as a by-product) not CO2 but water - which is a much cleaner form of emission.

    I believe that its only good for the city and not rural areas

    these cars are a very good alternative to cars that use fossil fuels but they only run short distances.
