Minimizing electrode contamination in an electrochemical cell

摘要

An electrochemical cell assembly that is expected to prevent or at least minimize electrode contamination includes one or more getters that trap a component or components leached from a first electrode and prevents or at least minimizes them from contaminating a second electrode.

1. A fuel cell assembly capable of preventing a component from an anode from contaminating a cathode of the assembly, comprising:
an anode; a getter electrode capable of trapping components that leach from the anode, the getter electrode comprising a metal mesh structure; a cathode; an ion exchange membrane between the anode and the getter electrode; an ion exchange membrane between the getter electrode and the cathode; and means for applying an electric potential between the anode and the cathode and between the anode and the getter electrode.
