SYSTEM FOR FLEXIBLE IN SITU CONTROL OF PRODUCT WATER IN FUEL CELLS

摘要

An electrochemical cell ( 100 ) includes an anode ( 110 ), a cathode ( 120 ) including a gas diffusion electrode and having first and second surfaces, an inlet for gaseous oxidant that is in contact with the first surface of the cathode ( 120 ), and a liquid electrolyte ( 130 ). Water generated at the cathode may be transported by osmosis into the liquid electrolyte. The fuel cell ( 100 ) may produce a current density of 200 mA/cm2 without cathode flooding.
