20100047631MEMBRANE ELECTRODE ASSEMBLY HAVING PROTECTIVE LAYER AND METHOD FOR MITIGATING MEMBRANE DECAY - A membrane electrode assembly includes an anode; a cathode; a membrane disposed between the anode and the cathode; and a protective layer positioned between the membrane and the cathode, the protective layer having a first side and a second side and being adapted to restrict migration of oxygen at the first side and to restrict the migration of hydrogen at the second side and thereby maintain a plane of potential change between the anode and the cathode within the protective layer.02-25-2010
20100068566METHOD FOR MINIMIZING MEMBRANE ELECTRODE DEGRADATION IN A FUEL CELL POWER PLANT - A method and apparatus for mitigating decay of multiple membrane electrode assemblies (03-18-2010
20100086811CONTROLLING AN AMOUNT OF LIQUID WITHIN A FUEL CELL - A method of controlling an amount of liquid in a fuel cell includes increasing the oxygen utilization within the fuel cell to increase heat. The heat reduces the amount of liquid in the fuel cell. A disclosed example method includes decreasing a supply of air to the fuel cell to lower a fuel cell voltage by increasing the oxygen utilization. The example method includes maintaining an essentially electrical current density while decreasing the supply of air.04-08-2010
