    • A method of heat treating a substrate for a fuel cell includes stacking substrates to form a group. A dimension is determined for a plate corresponding to a resulting mass that is less than a predetermined mass. The plate is arranged above the group to apply a weight of the plate to the group. The resulting masses for spacer plates and intermediate lifting plates, for example, are minimized to reduce the pressure differential between the bottom and top substrates in the heat treat assembly. In another disclosed method, a dimension for a plate, such as a top plate, is determined that corresponds to a resulting mass that is greater than a predetermined mass. The plate is arranged above the group to apply a weight of the plate to the group. The top plate resulting mass is selected to minimize a variation in the average pressure of the substrates throughout the heat treat assembly.
    • 一种用于燃料电池的基板的热处理方法包括堆叠基板以形成一组。 对于对应于小于预定质量的所得质量的板来确定尺寸。 板被布置在组上方以将板的重量施加到组。 例如,用于间隔板和中间提升板的所得质量被最小化以减少热处理组件中的底部和顶部基底之间的压力差。 在另一公开的方法中,确定板的尺寸,例如顶板,其对应于大于预定质量的所得质量。 板被布置在组上方以将板的重量施加到组。 选择顶板产生的质量以最小化整个热处理组件中的基底的平均压力的变化。

    • The invention includes an anode fuel flow field (100) adjacent a fuel cell (12) electrolyte (18) that defines a fuel path (102) between a fuel inlet (108) and a fuel outlet (110) and includes a cooler plate (118) in heat exchange relationship with the anode fuel flow field (100) that defines a coolant path (120) between a coolant inlet (126) and a coolant outlet (128). The fuel path (102) has a width (132) that is about the same as a width (134) of the coolant path (120) where the fuel path (102) and the coolant path (120) are closest to each other, and the fuel path (102) substantially overlies the coolant path (120) to minimize evaporation of water from water management flow fields (20) (22) and/or the electrolyte (18) into the fuel within the fuel path (102).

    • The invention reduces free water volume in a fuel cell power plant so support systems of the plant are freeze tolerant. The fuel cell power plant includes a coolant system having a sealed cooler plate that circulates an antifreeze coolant in heat exchange with a fuel cell and that collects fuel cell water; a water vapor removal system that removes water vapor from the antifreeze coolant to regulate the antifreeze concentration; and a start-up system having a start-up heat exchanger and a start-up valve that selectively direct heated antifreeze coolant into the cooler plate for a start-up procedure. The plant may also include a fuel processing system that utilizes the removed water vapor, and that is in heat exchange with the start-up heat exchanger. The antifreeze coolant is a low vapor pressure solution, such as an alkanetriol or polyethylene glycol.
