There is one crucial difference between hydrogen fuel cell cars and other electric vehicles hydrogen cars produce the electricity themselves.
How hydrogen fuel cell cars work. It only takes a minute or two to fill the. The protons and electrons reunite at the cathode and join with the oxygen to form water most of which become the fuel cells exhaust. Some leases may cover the cost of refueling entirely. Electric cars and plug in hybrids explained.
This initiative supported by legislation in the energy policy act of 2005 epact 2005 and the advanced energy initiative of 2006 aims to develop hydrogen fuel cell and infrastructure technologies to make fuel cell vehicles. Why car makers are once again turning to fuel cells. What makes a hydrogen car possible is a device called a fuel cell which converts hydrogen to electricity giving off only heat and water as byproductsbecause its non polluting hydrogen seems like the ideal fuel for the 21st century. Widespread use of fuel cell hydrogen cars could also potentially reduce the worlds.
The more fuel cells in the stack the greater the voltage of the electricity that the stack produces. Fuel cells are designed to be flat and thin mainly so they can be stacked. A lot of people in the government and the auto industry are excited about its potential. Toyota pioneer of hybrid cars is now betting on hydrogen fuel cells as a way of increasing the range of electric vehicles.
Hydrogen fuel cell cars return for another run by lawrence ulrich. Refueling a fuel cell vehicle is comparable to refueling a conventional car or truck. So unlike in fully electric or plug in hybrid vehicles the vehicle doesnt get its power from a built in battery that can be charged from an external power source read more. During the reaction hydrogen and oxygen combine to produce.
Bbc news 8 june 2015. The hydrogen fuel cell car emits only pure water at the tailpipe which is clean enough to drink and therefore does not contribute to local pollution. Interest in cars powered by hydrogen fuel cells has grown in recent years because fuel cells are more efficient and create less exhaust emissions than cars powered by conventional fossil fueled engines. A fuel cell produces electricity by means of electrochemical reactions between a fuel typically hydrogen and the oxygen in the air.
Just as hydrogen is forced into the fuel cell at the anode oxygen is forced in at the cathode. Pressurized hydrogen is sold at hydrogen refueling stations taking less than 10 minutes to fill current models. Youve probably heard about fuel cellsin 2003 president bush announced a program called the hydrogen fuel initiative hfi during his state of the union address.
