The human body is arguably one of the finest machines ever created by nature, and now a team from Norway’s Academy of 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 heading the team, making fuel cells in the shape of lungs could cut down on the amount of expensive catalysts needed, such as platinum, while increasing efficiency. It is hoped that the research will enable hydrogen cars to manufactured en mass.
