Gallery: Researchers Use Urea to Create Low-Cost Fuel Cells


Researchers at Heriot-Watt University in the United Kingdom have figured out how to use urea as a fuel for low-cost fuel cells. Fuel cells are a great form of alternative energy for all kinds of things — cars, submarines, remote power stations — but concern over the cost of hydrogen and its explosive nature keep the technology from being widely used. Using urea — which is present in all animal and human urine — instead of hydrogen could be a low cost alternative to these super low-emission systems.

    Is there such a thing as a direct urea fuel cell that can use a polymerized sulfur doped with potassium hydroxide and or with nickel oxide nano powder on electrodes to convert urea directly to electricity?

    I’m very much interested in this topic, I want to extract hydrogen from urine and by storing it by using any metal hydrides and use it as fuel for vehicles.please help me out in this regard

    This is an amazing article. I hope nothing negative comes out of the research being done. This could be a huge step in cleaning our planet and making our bathrooms more important.

    […] Science and Letters in Oslo are looking to it for inspiration as they design the next generation of hydrogen fuel cells. More specifically, they are looking at the lungs — according to Signe Kjelstrup, who is […]
