A Dynamic System for Removing Oxygen from Air Using an Electrochemical Cell

Specialized electrochemical cells, which have the ability to deoxygenate continuously, may provide an alternative method of minimizing deterioration in museum objects by display or storage in the absence of oxygen. A prototype has been investigated and its ability to reduce the oxygen concentration inside a small, airtight chamber, similar in shape and size to a museum display case, has been measured. Preliminary results are presented.
