Advancements in zero-emission fuel cells could make the technology inexpensive adequate to change standard gasoline engines in vehicles, according to researchers at the University of Waterloo.
The researchers have actually developed a brand-new fuel cell that lasts at least 10 times longer than present innovation, an enhancement that would make them economically practical, if mass-produced, to power automobiles with electricity.
” With our design approach, the expense might be similar and even more affordable than gasoline engines,” said Xianguo Li, director of the Fuel Cell and Green Energy Lab at Waterloo. “The future is extremely brilliant. This is clean energy that could grow.”
Researchers at first focused on hybrid cars, which now have gas engines as well as batteries due to concerns involving limited driving range and long charging times.
Existing fuel cells could in theory change those gas engines, which power generators to charge batteries while hybrid vehicles are in operation, however are unwise because they are too expensive.
The scientists solved that issue with a design that makes fuel cells much more durable by providing a constant, instead of fluctuating, amount of electrical power.

That implies the cells, which produce electricity from the chain reaction when hydrogen and oxygen are combined to make water, can be far easier and therefore far less expensive.
” We have discovered a method to lower costs and still satisfy durability and performance expectations,” stated Li, a teacher of mechanical and mechatronics engineering. “We’re fulfilling financial targets while providing no emissions for a transportation application.”
Scientists hope the introduction of fuel cells in hybrid automobiles will cause mass production and lower unit costs. That might pave the way for the replacement of both batteries and gas engines totally by offering an affordable, safe, trustworthy, tidy source of electrical power.
” This is a great initial step, a transition to what might be the response to the internal combustion engine and the huge ecological damage it does,” stated Li.
