Hydrogen generation using a fuel cell system with an REP

A fuel cell system includes a fuel cell having an anode and a cathode configured to output cathode exhaust. The fuel cell is configured to generate waste heat. The fuel cell system further includes a reformer configured to partially reform a feed gas using the waste heat and output a hydrogen-containing stream. The fuel cell system further includes a reformer-electrolyzer-purifier (“REP”) having an REP anode configured to receive a first portion of the hydrogen-containing stream and an REP cathode.

Heat recovery from an electrochemical hydrogen separation system

An EHS system includes a EHS cell having an anode, a cathode, and a cooling plate disposed proximate at least one of the anode or the cathode, the cooling plate configured to receive water and configured to output steam or a mixture of water and steam. The system further includes a liquid-vapor separator (LVS) configured to receive the steam or the mixture of water and steam from the cooling plate and to separate water and steam. The LVS is configured to output water to the cooling plate.
