Title:
FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/008686
Kind Code:
A1
Abstract:
This fuel cell system (1) is used in a building having, as building equipment; a hot water tank (4) which is installed on the ground or on a basement floor and replenished with room-temperature water via a water supply pipe (12); and a main heat source machine (6) that can heat the stored water inside the hot water tank (4). The fuel cell system (1) is provided with a fuel cell (7) that can supply power inside the building (2), and a preheating tank (5) disposed midway along the water supply pipe (12). In the preheating tank (5), heat recovery from an off gas of the fuel cell (7) causes the stored water to be preheated and the off gas to be cooled. The room-temperature water replenished via the water supply pipe (12) is used as the heat source for cooling the off gas in the preheating tank (5). Condensate water generated by cooling the off gas is reused in the fuel cell (7).
