Abstract:
1. A method, comprising: measuring a property of an electrochemical system; correlating the measured property to a concentration of an anode species in an anode of an electrochemical device associated with the electrochemical system; controlling the introduction of at least one of a fuel and oxygen to the electrochemical device based at least in part upon the concentration of the anode species in the anode of the electrochemical device; flowing the fuel into the electrochemical device through a restriction sized and adapted to provide an upstream to downstream pressure ratio across the restriction of at least 1.1:1; flowing the fuel into a bottom portion of an anode compartment of the electrochemical device, the anode compartment having the bottom portion and a wall ascending from the bottom portion; forming a bubble of the fuel on the bottom portion of the anode compartment until the bubble contacts the wall of the anode compartment; allowing the bubble to travel up the wall of the anode compartment.
