Abstract:
A humidification system using an injector for a fuel cell stack includes: a fuel cell separator including a reaction flow field, and an air inlet port and an air outlet port formed at a front portion and an end portion of the reaction flow field, respectively; a humidification chamber provided at a part of or the whole length of the front portion of the reaction flow field of the separator; and an injector mounted at a starting point of the humidification chamber to inject a mixture of water and air into the humidification chamber. With the system, humidification efficiency can be improved and/or maximized without an increase in the volume of the fuel cell stack.

A scan driver sequentially activates scan lines of a display apparatus having m-number of scan lines. The scan driver includes a pull-up driving section and a pull-down driving section. The pull-up driving section includes a pull-up transistor that is electrically connected to an ith scan line to activate the ith scan line to be in a high level state. The pull-down driving section includes a pull-down transistor that is electrically connected to the ith scan line to inactivate the ith scan line to be in a low level state when (i+1)th scan line is activated. A gate electrode of the pull-up transistor is electrically separated from the ith scan line. The above ‘m’ is an integer greater than 1, and ‘i’ is an integer no greater than ‘m’. Therefore, display defects may be minimized, and detecting a cause of the display defect may be simplified to enhance productivity.
