  • Patent number: 6673481
    Abstract: A vehicle (150) includes a fuel cell stack (151) started when the stack is below freezing, by connection (158) to the vehicle propulsion system (159) within a few seconds of starting the flow of fuel (179) and oxidant (173), or when open circuit voltage (155, 156) is detected. The fuel is in excess of stochiometry requirement and the oxidant is in excess of at least twice stochiometric requirement, either may be at about atmospheric pressure or at 4 kPa (0.6 psi) or more above the pressure of any water in said water passages, and either may be below freezing. Water transport plates (84, 86, 88, 89) have water passages connected to a water circulation loop (170) including a reservoir (164) having an auxiliary heater (161) connected (160) to the stack. Warming of cell stack materials and ice in the water transport plates, heat of fusion of melting ice, warming of melted water, and evaporative cooling of water melted in the water transport plates keep the fuel cell cool until liquid coolant can be circulated.

  • Patent number: 6673488
    Abstract: A battery comprised of a generally rectangular electrochemical cell that has two battery leads attached to current collectors extending from one side thereof. A package formed from a sheet laminate has a cavity formed therein that defines an opening for receiving the cell and portions of the leads. A flange extends around the opening. A cover overlays the cavity and the flange. The cover is joined to the flange and forms a seal that hermetically seals the electrochemical cell within the cavity. The package has two, non-rectangular corners. The cover and the flange in the vicinity of the corners are shaped to allow the flange to be bent along the at least three sides in a manner wherein the flange is positioned adjacent the three sides, but the flange is not tucked or overlapped onto itself at the two, non-rectangular corners.
