Title: Heat recovery from an electrochemical hydrogen separation system

Abstract

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.
