Abstract
A fuel cell system includes: a plurality of fuel cell modules each including a fuel cell stack and a cooling device that cools the fuel cell stack; a coupled cooling circuit in which cooling circuits respectively included in the plurality of fuel cell modules are connected in parallel to one another; and an ion exchange device connected to the coupled cooling circuit and including a plurality of ion exchangers. A switching valve that selectively switches a flow of coolant to the plurality of ion exchangers allows the coolant to flow through only one of the plurality of ion exchangers.
Claims7
A fuel cell system comprising:
- a plurality of fuel cell modules each including a fuel cell stack configured to generate electric power by being supplied with oxygen-containing gas and fuel gas, and a cooling device configured to cool the fuel cell stack by allowing coolant to flow through the fuel cell stack;
- the cooling devices respectively included in the plurality of fuel cell modules;
- a coupled cooling circuit in which a plurality of cooling circuits respectively included in the plurality of cooling devices are connected in parallel to one another;
- and
- an ion exchange device connected to the coupled cooling circuit and including a plurality of ion exchangers,
- wherein the ion exchange device includes a switching valve configured to selectively switch a flow of coolant to the plurality of ion exchangers, and the switching valve allows coolant to flow through only one of the plurality of ion exchangers.
