Title:
FUEL CELL CO-GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/209031
Kind Code:
A1
Abstract:
This fuel cell co-generation system (1) comprises: a fuel cell (2); a cooling water tank (3) storing cooling water for recovering heat generated by the fuel cell (2); a cooling water pump (4) for circulating the cooling water; a heat exchanger (5) for recovering the heat from the cooling water in waste heat recovery water; and a hot water circulation pump (7) which supplies the waste heat recovery water. This fuel cell co-generation system (1) also comprises a heat recovery high temperature path (8B) for supplying water from the heat exchanger 5 to a hot water tank (6), and a heat recovery low temperature path (8A) for supplying the waste heat recovery water from the hot water tank (6). In addition, this fuel cell co-generation system (1) comprises a determination unit (10) for determining, from the output signal of the hot water circulation pump (7), whether the heat recovery high temperature path (8B) and the heat recovery low temperature path (8A) are connected erroneously. In this manner, an erroneous connection is detected quickly.
