The researchers say this dual activity could significantly reduce the costs associated with current water treatment in industrialized countries and make such treatment more widely available in developing countries.

The prototype fuel cell consists of a cylindrical Plexiglas chamber, 15 centimeters long and 6.5 cm wide, in which the researchers arranged eight graphite rods around a hollow carbon-and-platinum tube. The rods serve as ne
