Abstract: Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures may be observed by minimizing the coolant volume in the coolant subsystem. In particular, this may be accomplished by having a two pump—dual loop cooling subsystem. During startup, one pump directs coolant through a startup coolant loop and after either the fuel cell stack or the coolant temperature reaches a predetermined threshold value, coolant from a main or standard coolant loop is then directed to the fuel cell stack. In an embodiment, coolant from the standard loop mixes with coolant in the startup loop after the predetermined threshold temperature is reached.

Abstract: To represent the motion of a pixel between successive image frames, this method utilizes the motion information for the transformation block containing the pixel, as well as the motion information for adjacent transformation blocks whenever the adjacent transformation blocks are associated with the same object with which the selected pixel is associated. As a result, transformation errors arising from transformation block discontinuities are decreased and the accuracy and integrity of motion representations of pixels within an object are maintained. Preferably, the motion representations for the transformation blocks are multi-dimensional or affine transformations that are capable of representing complex motions that include any or all of translation, rotation, magnification, and shear.

Abstract: Performance in solid polymer electrolyte fuel cells can be improved by varying the characteristics of the ionomer used in the electrode of a membrane electrode assembly. For instance, increasing the ionomer to catalyst ratio can allow for improved performance under drier operating conditions (e.g., when less humidified reactants or higher operating temperatures are used) or when starting up in below freezing conditions.

Abstract: Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures are obtained by utilizing an insulated fuel cell stack in combination with an thermal control subsystem. Temperature of the insulated electrochemical fuel cell stack, as well as temperature of the ambient environment, are monitored and a heating fluid is heated by thermal transfer with the environment under appropriate thermal conditions. The heated fluid is then passed to the insulated fuel cell in order to increase the temperature of the same, typically to a temperature at or near the temperature of the ambient environment. In this manner, ambient heat from the environment is utilized to increase the temperature of the insulated fuel cell stack, thus improving conditions for subsequent cold start of the insulated fuel cell stack.
