The everyday liquid that could fuel China’s race to green car targets




Scientists in China and Australia have developed a catalyst which uses urea-loaded waste water to efficiently generate clean energy, paving the way for low-cost portable fuel cells that work like batteries.Fuel cells, which have been used to power electric vehicles, are a clean source of electricity. They produce power through an electrochemical reaction of hydrogen with oxygen, generating heat and water as by-products.The new technique oxidises urea – an abundant substance in human and animal…
