The present invention relates to a fluid circulation type heating device which circulates fluid by means of heating and cooling and, more particularly, to a fluid circulation type heating device provided with overpressure protection element which can prevent pressure increase of a circulation path of a fluid. The fluid circulation type heating device according to the present invention for achieving the aforementioned purpose comprises a circulation line, a heat radiation member installed on the circulation line, a boiler which heats and expands a fluid, a storage tank which stores the fluid therein and supplies the same to the boiler, a controller which controls the boiler, and a housing which accommodates the boiler and the controller. In addition, the device has an opening formed in fluid communication with the storage tank or the circulation line, and further comprises an overpressure protection element which blocks the opening, wherein the overpressure protection element is configured to prevent fluid from passing through and allowing a vapor of the fluid to pass through, thereby dropping the pressure of the storage tank and the circulation line. The fluid circulation type heating device according to the present invention discharges, to the outside, steam from the inside of a circulation path and does not discharge fluid to the outside, thereby preventing overpressure loaded onto the fluid circulation path of a heating device. In addition, should the heating device fall over, it is possible to prevent fluid from being discharged to the outside. Furthermore, it is possible to prevent external foreign material from being introduced into the circulation path, thereby preventing damages of components or generation of odor, due to contamination of fluid caused from the external foreign material.

The present invention relates to a solid oxide fuel cell (SOFC). According to the present invention, provided is a solid oxide fuel cell comprising single cells, first and second side plates coupled to either side of a stack of such single cells, and first and second current collectors arranged among the single cells. Each single cell has a first surface, and a second surface formed in parallel with the first surface. First channels having cathodes and second channels having anodes are formed in parallel with each other in the direction parallel to the first surface and second surface. A first current-collecting layer, which is electrically connected to the cathodes, is formed on the first surface, and a second current-collecting layer, which is electrically connected to the anodes, is formed on the second surface. The single cells are stacked such that the first surfaces and second surfaces of the single cells contact each other. The solid oxide fuel cell of the present invention eliminates the necessity of arranging a separate structure, such as a cover or a cap, between the single cells of an upper layer and a lower layer, thereby increasing output per unit volume.
