20140072893 | POWERING A FUEL CELL STACK DURING STANDBY - A system and method for limiting voltage cycling of a fuel cell stack during a stand-by mode by providing power from a battery to the stack while the stack is turned off. The method includes monitoring the voltage of each of the fuel cells in the fuel cell stack and determining an average cell voltage of the fuel cells in the fuel cell stack. The method also determines whether the average cell voltage of the fuel cells in the fuel cell stack has fallen below a predetermined voltage value and, if so, applies a voltage potential to the fuel cell stack to increase the average cell voltage above the predetermined voltage value. | 03-13-2014 |

20160064741 | ELECTRODE DESIGN WITH OPTIMAL IONOMER CONTENT FOR POLYMER ELECTROLYTE MEMBRANE FUEL CELL - A method of making a membrane electrode assembly for a fuel cell, a membrane electrode assembly, a fuel cell and a fuel cell system. The method includes preferentially adsorbing an ionomer and electrocatalyst mixture onto the surface of a porous fuel cell substrate by appropriate treatment of the mixture prior to or contemporaneous with placement of the mixture onto the substrate. This promotes retention of the ionomer-coated electrocatalyst at or near the surface of the substrate where catalytic activity between it and a proton exchange membrane is designed to take place. Retention of the ionomer-coated electrocatalyst near these interfacial regions by the present invention is preferable to having the ionomer and electrocatalyst be significantly absorbed into the substrate. | 03-03-2016 |
