Abstract: The present disclosure relates to a forklift. The forklift according to the present disclosure is controlled such that when a traveling speed reaches or becomes higher than a predetermined traveling speed, a flow rate of hydraulic oil to be provided to a steering unit is reduced. Therefore, in order to implement a desired direction change, a steering wheel needs to be rotated to a relatively larger degree than when the forklift travels at a low speed. That is, straight traveling performance may be improved by reducing sensitivity of a direction change of the forklift to an operation of the steering wheel.

Abstract: A fuel cell separator, a fuel cell stack having the fuel cell separator, and a reactant gas control method of the fuel cell stack are provided. That is, even when the fuel cell stack operates under the low load operation condition, a reactant gas is supplied to the reactant gas passages of the fuel cell separator, and thus, the length of the passage can be shortened by 50% as compared with the prior art having only one reactant gas passage. Therefore, the reactant gas can be effectively supplied without experiencing pressure loss. Further, in the high load operation of the fuel cell stack, the reactant gas is introduced into the first reactant gas passage of the fuel cell separator and utilized in half of the whole electrode area. Subsequently, the reactant gas is introduced into the second reactant gas passage and utilized in the remaining half of the electrode area.
