  • Hydrogen fuel cells provide power when fuel supply is off

    Updated: 2012-07-11 15:20:01
    (Phys.org) -- Fuel cells, which generate electricity from the chemical energy of a fuel such as hydrogen, are not intrinsically capable of storing energy. When a fuel cell’s hydrogen supply runs out or is temporarily interrupted, the cell’s power output quickly decreases to zero. If an application requires energy storage, then the fuel cell must be coupled to an external charge storage device, such as a battery, which increases the weight and volume of the system. But now researchers have designed a hydrogen fuel cell with a new anode that can supply electricity up to 14 times longer than conventional fuel cells, which could be particularly useful for mobile energy applications.
