20110008715 | PLATINUM LOADED SUBSTRATE FOR A FUEL CELL AND METHOD FOR PRODUCING SAME - A method of depositing platinum onto a support is disclosed. This method is based on a combination of two processes: electrochemical and electroless deposition, using a chemical bath containing a platinum source and agents that trigger nucleation and buffer the solution. This method is capable of producing a catalyst having a gravimetric current density of at least approximately 0.8 mA/cm2 per ?g of platinum per cm2 at cell voltage of 0.9V/RHE for oxygen reduction reaction. | 01-13-2011 |
20110207004 | POROUS FLOW FIELD PLATE FOR MOISTURE DISTRIBUTION CONTROL IN A FUEL CELL - A flow field plate for use in a fuel cell includes a porous, wettable plate body including a first reactant gas channel having an inlet portion, a second reactant gas channel having an outlet portion that is adjacent the inlet portion of the first reactant gas channel, and at least one moisture reservoir fluidly connected with pores of the porous, wettable plate body. The at least one moisture reservoir can selectively collect and release moisture received from a reactant gas in the outlet portion to thereby selectively move the moisture from the outlet portion toward the adjacent inlet portion. | 08-25-2011 |
20110294026 | Method and apparatus for controlling the operation of a fuel cell - A fuel cell system includes a fuel cell, a controller, a resistance sensor, and a regulator. The fuel cell has a cathode plate, an anode plate, and an ion-exchange membrane interposed between the cathode plate and the anode plate. The controller is for controlling a gas flow rate to the anode plate. The resistance sensor is coupled to the fuel cell for measuring a resistance of the fuel cell. The regulator is coupled to the controller and coupled to the anode plate for regulating the gas flow to the anode plate. The controller receives a signal from the resistance sensor and is configured to control the regulator to adjust the gas flow to the anode plate based on the signal from the resistance sensor. | 12-01-2011 |
