Abstract
A system and technique for purging condensate from an electrochemical cell stack prior to operating the stack in one of a power producing mode of operation and an electrochemical pumping mode of operation is provided. The system and technique include storing hydrogen in the anode and cathode chambers of the stack to place the stack in a shutdown state, purging the anode and cathode chambers of condensate prior to starting operation of the stack, and preventing a fuel starvation condition in the stack while purging by sequencing communication of a fuel flow and an oxidant flow to the anode chamber with an oxidant flow to the cathode chamber while purging the condensate.
