METHOD OF DISCHARGING REACTION WATER IN PEM FUEL CELLS, AND RESPECTIVE PEM FUEL CELL

摘要

Discharging reaction water in PEM fuel cellsIn PEM fuel cells, discharging the reaction waterdoes not require humidification of the reaction gases or anincrease in the gas pressure if a hydrophobic layer on thecathode side is used which has a smaller pore size than thelayer on the anode side; the reaction water is then removedvia the anode.
