This is clean energy that could boom," Li said.[br][br]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.[br][br]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.[br][br]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.[br][br]That means the cells, which produce electricity from the chemical reaction when hydrogen and oxygen are combined to make water, can be far simpler and therefore far cheaper.[br][br]"We have found a way to lower costs and still satisfy durability and performance expectations," said Li.[br][br]"We are meeting economic targets while providing zero emissions for a transportation application," said Li.[br][br]Researchers hope the introduction of fuel cells in hybrid vehicles will lead to mass production and lower unit costs.[br][br]That could pave the way for the replacement of both batteries and gas engines entirely by providing an affordable, safe, dependable, clean source of electrical power.[br][br]"This is a good first step, a transition to what could be the answer to the internal combustion engine and the enormous environmental harm it does," said Li.[br][br]Source: https://www.wap.business-standard.com/article-amp/pti-stories/cheaper-fuel-cells-could-replace-gas-engines-in-vehicles-119050800680_1.html[br]
