rn EVs but they are by no means the only available technology. A number of alternatives are under development and they, too, are well positioned to rival batteries as an effective EV power source. The First One Is fuel cells Some of the most recent and exciting news in electric-vehicle development has centered around a new power source, called the fuel cell. The fuel cell utilizes a special membrane to generate electricity through the controlled reaction between hydrogen and oxygen atoms. Unlike batteries, which store electricity rather than generate it, fuel cells actually produce electricity through a controlled chemical reaction between hydrogen and oxygen. Inside a fuel cell, the two elements are fed to opposite sides of a porous membrane. As hydrogen atoms pass through the pores, they are stripped of their electrons. This results in a negative charge on the membrane's hydrogen side and a positive charge on the oxygen side. Stacking fuel cells in series produces enough pow!

nnovative system-hydrogen is extremely explosive. It is also difficult to store and unavailable at local filling stations. Chrysler Corporation is currently working on a fuel cell that eliminates some of these obstacles, notably storage and inconvenience. Their efforts may make fuel cells a viable option in the near future. One of Chrysler's plans is to use small amounts of gasoline in fuel cells. Doing so would eliminate the dangerous proposition of storing hydrogen onboard an EV before converting it to electricity. A series of reaction chambers in the system would convert the gasoline to hydrogen as needed, and carbon monoxide-produced as a byproduct-would be processed in additional chambers that would convert it to harmless carbon dioxide. 2.Flywheels Another departure from chemical-based battery technology is the flywheel.
