The researchers have developed a new fuel cell that lasts at least 10 times longer than current technology, an improvement that would make them economically practical, if mass-produced, to power vehicles with electricity.
"With our design approach, the cost could be comparable or even cheaper than gasoline engines," said Xianguo Li, director of the Fuel Cell and Green Energy Lab at Waterloo. "The future is very bright. This is clean energy that could boom."
Researchers - Vehicles - Gas - Engines - Batteries
Researchers initially concentrated on hybrid vehicles, which now have gas engines as well as batteries due to issues involving limited driving range and long charging times.
Existing fuel cells could theoretically replace those gas engines, which power generators to recharge batteries while hybrid vehicles are in operation, but are impractical because they are too expensive.
Researchers - Problem - Design - Fuel - Cells
The researchers solved that problem with a design that makes fuel cells far more durable by delivering a constant, rather than fluctuating, amount of electricity.
That means the cells, which produce electricity from the chemical reaction when hydrogen and oxygen are combined...
