Rechargeable batteries and fuel cells are seen as the two contenders to serve as a power source for the next generation of environmentally friendly vehicles. A significant barrier to achieving greater efficiency in the latter is the slow rate of oxygen production from the cathode, which limits the power output of the device. Now an unexpected find by MIT researchers regarding the behavior of incredibly thin sheets of material could lead to major improvements .
