1. A cooling circuit operable with fuel of a fuel cell system, comprising:
a fuel tank storing fuel for the fuel cell system;
a fuel compressor configured to increase a pressure of the fuel;
a first heat exchanger configured to cool the pressurized fuel;
a first conduit coupled to an outlet of the first heat exchanger;
a first turbine coupled to the first conduit and configured to expand the pressurized and cooled fuel;
a second conduit coupled to an outlet of the first turbine and configured to direct the expanded fuel to the fuel cell system; and,
a third conduit connecting the fuel tank with the fuel compressor;
wherein the fuel compressor includes a first compression stage and a second compression stage;
wherein an outlet of the first compression stage, or an outlet of the second compression stage, or both the outlet of the first compression stage and the outlet of the second compression stage are coupled to a fourth conduit configured to direct compressed fuel to the first heat exchanger.
