ABSTRACT:
An electrochemical cell includes an anode, a cathode 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, and a liquid electrolyte. Water generated at the cathode may be transported by osmosis into the liquid electrolyte. The fuel cell may produce a current density of 200 mA/cm2without cathode flooding.
