Abstract: The present invention relates to a method for preparing an inorganic compound using desulfurization gypsum for reducing greenhouse gas emissions, and, more specifically, to a method for preparing an inorganic compound, in which calcium sulfate and calcium carbonate, which have various uses as construction materials and the like, can be prepared using, as raw material, desulfurization gypsum which, being a recycled resource, is industrial waste, and an extraction agent, and the extraction agent can be reused after separation, and thus, compared to existing processes, greenhouse gases and manufacturing costs can be remarkably reduced.

Abstract: A common distribution device of a fuel cell of a vehicle is provided where a first module and a second module comprises an air supplying portion and an air discharging portion are disposed below in the stack, and a third module and a fourth module which comprises a hydrogen supplying portion and a hydrogen discharging portion are disposed above in a stack. The fluid can be uniformly discharged from the stack during acceleration, deceleration, and tilting of a vehicle.
