cars powered by fuel cell are really electric cars. The electric motor feeds the energy generated by the chemical reaction between the hydrogen stored in tanks of high-pressure and the atmospheric oxygen or another oxidizing agent. It is a very simplified definition of your operation, but it is enough. A good example is the Toyota Mirai FCV. Nissan has developed a fuel cell capable of using ethanol, a biofuel pure, to generate electricity. A pioneering innovation in the automotive world.
Nissan has christened this system as e-Bio Fuel-Cell, and the promise of a higher efficiency in the use of fossil fuels.
The operation of this fuel cell is equal to that of a fuel cell powered by hydrogen, but it has more advantages on paper. The fuel cell feeds on biofuels pure, which are mixed with atmospheric oxygen and transformed into electrical energy in the fuel cell, after its electric charge, in a step prior to this last reaction chemical. The a result of the process are carbon dioxide emissions and electric energy for the electric motor that moves the wheels of the car.
Imagine a Nissan Leaf that instead of being plugged in you only need to go to the gas station. The use of biofuels is about the ideal role: neutralize the carbon dioxide emitted during their growth phase – usually extracted from sugar cane or maize, and are easily produced, reducing dependence on traditional fossil fuels. do Not require the use of tanks of high pressure as the cars of hydrogen, and both its cost and autonomy of operation is comparable to that of gasoline.
The car would lead as an electrical, with instantaneous power and the quiet operation so enjoyable. Nissan claims that this solution is ideal for cars and commercial vehicles, with a packaging size very content and an existing infrastructure. The side that is not so nice of biofuels is deforestation produced by these crops, and the allocation of fertile land to the production of fuels, not food. How is this responsibly in a world increasingly populated?
In the future, this fuel cell is created by Nissan could use natural gas and even water mixed with ethanol. The possibilities are high, but are yet to develop. Meanwhile, we understand that the electric vehicle will continue to be imposed to the internal combustion, although they could live among themselves without too many problems.
