1. A fuel cell system comprising:
a fuel cell configured to receive a partially reformed feed gas, the fuel cell comprising:
an anode, and
a cathode configured to output cathode exhaust, wherein:
the fuel cell is configured to generate waste heat;
a reformer configured to partially reform a feed gas comprising fuel from a fuel supply using the waste heat and output the partially reformed feed gas comprising a hydrogen-containing stream;
a reformer-electrolyzer-purifier (“REP”) comprising:
an REP anode configured to receive a first portion of the hydrogen-containing stream, and
an REP cathode; and
an indirect reforming unit disposed on the anode, which is configured to further reform the hydrogen-containing stream and output a fuel turn gas.
