How does fuel cells produce electricity or energy give at least one positive factor for that form of energy?

Answer 1

By the combination of H and O to form water. It is non polluting.

Answer 2

Fuel cell vehicles are not hybrids. the hydrogen (or methane) is used to produce electricity that run motors that drive the wheels. if the definition of a hybrid was 2 forms of energy are used.. any internal combustion vehicles (i.e., regular cars) could be called hybrids because they use gasoline and they have alternators that produce electricity.. however, these are not hybrids Hybrids drive trains have two entirely separate power sources and may or may not use regenerative braking to recharge one of those energy sources. A conventional hybrid has an electric motor and an internal combustion motor.... so it is gas and electric.. and the car can actually be run on either source separately.. GM's new volt system will have both an electric power source and a backup internal combustion system.. however it is NOT a hybrid. The internal combustion system runs a generator that recharges the batteries that run the electric power source

Answer 3

how they work is explained really well here. http://inventors.about.com/od/sstartinventions/ss/Physics_Illustr_2.htm

Advantages Include no emissions besides heat and water. as well as being a renuable energy source.
