1. A fuel cell system, comprising:
a fuel cell stack;
an anode exhaust conduit configured to receive an anode exhaust from the stack;
a water injector configured to inject water into the anode exhaust in the anode exhaust conduit;
an anode recuperator configured to receive the anode exhaust from the stack, to heat fuel provided to the stack using heat from the anode exhaust and to provide the anode exhaust to the anode exhaust conduit and the water injector;
an anode tail gas oxidizer; and
a splitter configured to direct a first portion of the anode exhaust provided from the anode recuperator into the anode exhaust conduit and the water injector, and to direct a second portion of the anode exhaust provided from the anode recuperator into the anode tail gas oxidizer.
