The present invention provides a separator for a fuel cell, in which a water discharge hole such as a venturi tube or a water discharge means including a metal plate for condensing water is provided on a land of the separator being in contact with a gas diffusion layer of a fuel cell so that water generated by a reaction is easily discharged from the GDL through the water discharge means. At least one electrical connector is configured to connect one end of a first LED PCB to an end of a second said LED PCB such that the first and second LED PCBs are electrically connected end-to-end. A color projection mechanism selectively changes the color of the object. The vehicle control unit may further evaluate work efficacy of the vehicle based upon the calculated vehicle speed and communicate display data of the results to an operator of the vehicle. In this manner, a visually impaired user is able to perceive a 3-dimensional object.
