Hydrogen Fuel Cell

The hydrogen fuel cell works on the basis of electrolysis process. It generates electricity with fuel on the anode side and the oxidant on the cathode side and they react in the presence of electrolyte. The reactants which are the input flows into the cells and the reactant products flow out of it while the electrolyte remains inside it. The hydrogen fuel cell is just like the water fuel cell which was a failure. However the hydrogen fuel cell is a success. The fuel cells can run continuously if the input is maintained properly.

Hence the hydrogen fuel cell is just like the petrol engine and I must tell you that it works fine as well. However the fuel cells are different from the electrolytic cells as they consume the reactant from the external source, which requires a thermodynamically open system. Many combinations of the fuel and the oxidants are possible. For example the hydrogen cell uses the hydrogen as the fuel and oxygen as the oxidant. The other combinations are hydrocarbon and alcohol as well as chlorine and chlorine dioxide.

The fuel cell works with the help of electrolysis. Up till now you must have understood the use of reactant as well as oxidants. However you will have to understand one more thing and that is catalysis. The fuel cell works with the help of catalysis which helps in separating the electrons and protons. Now you must know that the electric current flows in the direction opposite to the flow of the electron. I must say that the electron flow is maintained with the help of catalysis which separates the electron and proton and hence the electrons start moving in one direction and hence the electricity is generated.

A typical hydrogen fuel cell produces about 0.6 to 0.7 volts of voltage. However this cell does not obey the ohms law. You must know that according to Ohms law the voltage is directly proportional to the current. However this is not the case with the hydrogen fuel cell. In case of the hydrogen fuel cell the voltage is found to go o decreasing as the current starts increasing.

The reason behind the decrease in the voltage is because of the facts that are as follows:

1. Activation loss
2. Ohmic loss: (due to the resistance of the cell components and interconnect.)
3. Mass transport loss (due to the depletion of the reactants at the catalyst site.)

Hence it is a general observation that the hydrogen fuel cell do not obeys Ohms law. In fact all the electrolytic cells do not obey the ohms law and hence hydrogen fuel cell which is also a kind of electrolytic cell does not obey the ohms law.

Hydrogen Fuel Cell Technology

When you use water to run your car then in fact you are using the hydrogen fuel cell technology. This technology is latest in the news and it is an attempt by the scientists and engineers to make your vehicle less polluting.

Although eighty years old but the technology is taking waves as it makes the vehicle more environment friendly besides being an alternative to the petrol and diesel, the main fuel on which our car and bikes speed on roads.

The technology uses the fuel cell that has two electrodes and water. As the electricity passes the water molecule is broken down into hydrogen and oxygen. This chemical process is called as electrolysis. The hydrogen gas thus formed is passed to the fuel chamber where it is absorbed and promotes for the more efficient use of the fuel that we are using. Such assembly of electrodes is available in the market in the form of kits. You can fix these kits to your car.

Although biofuel, vegetable fuel are available as an alternative technologies for petrol and diesel but these have their own limitations. It gets costly to develop biodiesel from sugarcane. The source of the diesel is produced in certain climates thus this also act as the limitation. But such restriction is ruled out in the hydrogen fuel technology as the water is freely available and can be electrolyzed to make your car more efficient. The efficiency is increased by 70%-80%. Thus your car uses less of the petrol emits less pollutant and thus become more ecofriendly.

You can also prepare these hydrogen kits in your own garage. Remember your school days when you performed various science experiments in the lab. It's all that exciting and simple. All you have to do is go to the market and purchase all the essential things. Follow the instructions on the instruction manual. If you don't want to experiment then you can directly purchase the assembled kit available in the market.

You can search the internet and you will get all the options, the different designs and their prices. Browse through the catalogue and purchase the kit online sitting comfortably in your living room.
So contribute a little to conserve your planet by using this technology. You will not only make your environment less polluted but also save a lot of money by saving on the petrol.

Make your pocket grow bigger and your environment better to breathe in by using this environment friendly hydrogen fuel cell technology.

Go green!
