  • Permselective composite membrane for electrochemical cells
    Patent number: 8158300
    Abstract: An electrochemical cell includes an anode including an anode catalyst, a cathode including a cathode catalyst, and a first set of proton-conducting metal nanoparticles between the anode and the cathode, such that the first set of proton-conducting metal nanoparticles is not in contact with the anode. The cathode may be a cathode assembly including a gas diffusion electrode, a cathode catalyst on the gas diffusion electrode, and proton-conducting metal nanoparticles on the cathode catalyst.

  • System for flexible in situ control of water in fuel cells
    Patent number: 7901817
    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/cm2 without cathode flooding.
