FUEL CELL UNIT INCLUDING AN EXCHANGEABLE DEIONIZATION DEVICE AND A VEHICLE INCLUDING SUCH A FUEL CELL UNIT
A fuel cell unit having at least one fuel cell, a cooling circuit and a deionization device ( 10 ). The deionization device includes a housing ( 16 ) and a deionizing agent ( 11 ) located therein A vehicle is also provided having such a fuel cell unit. It is provided that the deionization device ( 10 ) can be or is connected in a fluid-conveying manner to the cooling circuit ( 5 ) with a single connection unit ( 15 ) via a flow inlet ( 13 ) and a flow outlet ( 14 ).
1 - 10 . (canceled)
11 . A fuel cell unit comprising:
at least one fuel cell;
a cooling circuit; and
a deionization device including a housing and a deionizing agent situated in the housing, the deionization device connectable or connected to the cooling circuit in a fluid-conveying manner via a flow inlet and a flow outlet with the aid of a single connection unit.
12 . The fuel cell unit as recited in claim 11 wherein the flow inlet and the flow outlet are for a coolant and are situated on a same side of the housing of the deionization device.
13 . The fuel cell unit as recited in claim 11 wherein the housing of the deionization device is designed as a vessel open on one side, and is connectable or connected to the connection unit via the open side.
14 . The fuel cell unit as recited in claim 11 wherein a connection between the connection unit and the deionization device is designed as a plug connection or a rotary joint.
15 . The fuel cell unit as recited in claim 14 wherein the connection between the connection unit and the deionization device is designed as a bolted connection, a bayonet joint, or a snap-in connection.
16 . The fuel cell unit as recited in claim 11 wherein the connection unit includes an active or passive closure mechanism for closing and opening the flow inlet and the flow outlet of the deionization device.
17 . The fuel cell unit as recited in claim 11 wherein the deionizing agent is a filling made up of an ion exchange resin, a coolant flowable around the ion exchange resin.
18 . The fuel cell unit as recited claim 11 wherein the deionization device further includes a permeable filter element situated within the housing and separating the deionizing agent from the flow outlet.
19 . The fuel cell unit as recited in claim 11 wherein a coolant of the cooling circuit includes water, an antifreeze fluid, and at least one corrosion inhibitor.
20 . A vehicle comprising the fuel cell unit as recited in claim 11 .
