LOW-TEMPERATURE FUEL CELL HAVING AN INTEGRATED WATER MANAGEMENT SYSTEM FOR PASSIVELY DISCHARGING PRODUCT WATER

摘要

A low-temperature fuel cell having an integrated water management system for passive discharge of product water includes at least one membrane-electrode assembly having at least one anode-side and one cathode-side electrode and at least one membrane disposed between the electrodes, current collector structures disposed on the anode-side and cathode-side and distribution structures for fuel and oxidant disposed on the anode-side and cathode-side. The cathode-side distribution structure hereby has a capillary structure for transporting away the product water and also gas supply channels.
