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.
