A dehydrogenation reaction apparatus and a system including the same are disclosed. The dehydrogenation reaction apparatus includes: a main housing; and a dehydrogenation reactor which is provided inside of the main housing and has a catalyst provided inside. In particular, the dehydrogenation reactor generates hydrogen from a liquid organic hydrogen carrier (LOHC). The dehydrogenation reaction apparatus further includes: a heating device provided inside of the main housing and configured to apply heat to the dehydrogenation reactor through a phase change material, where the phase change material is provided between the main housing, and the dehydrogenation reactor and the heating device.

A plurality of channel elements provided in a bipolar plate have different widths depending on positions, so that the velocity of flow of the fluid increases from an inlet toward an outlet of the bipolar plate and water generated when the fluid is condensed on the downstream side of the bipolar plate can be discharged more smoothly. In addition, a plurality of channel elements have different contact angles depending on positions of the plurality of channel elements so that the contact angle increases toward the outlet side of the bipolar plate. Thus, the reaction gas can be more concentrated on the surface of a gas diffusion layer. Even if the concentration of the reaction gas is reduced at the outlet side of the bipolar plate, the diffusion of the reaction gas is well performed, so that performance reduction can be prevented.

A lithium-air battery system using a vortex tube is provided, in which the vortex tube is connected to an oxygen supply port of a lithium-air battery having a stack form. A high-temperature gas generated in the vortex tube is supplied to the lithium-air battery to induce a stimulating reaction and simultaneously, a low-temperature gas generated in the vortex tube is supplied to a cooling path in the lithium-air battery to realize efficient cooling of the lithium-air battery.
