  • Method of discharging reaction water in PEM fuel cells and fuel cell for carrying out the method
    Publication number: 20010038933
    Abstract: Discharging the reaction water from the novel PEM fuel cells does not require humidification of the reaction gases or an increase in the gas pressure. This is attained in that a hydrophobic layer on the cathode side is used which has a smaller pore size than the layer on the anode side. The reaction water is removed via the anode during the operation of the fuel cell.
