Engineering360: "Efficient CO2 Conversion with New Electrochemical Cells"

Something doesn't look right to me.

• The title and first part of the article use CO₂, but later in the article there is no mention of CO₂ conversion, the 2 is dropped and uses CO.
• The diagram also shows CO, not CO₂.
• On the diagram, the balance of ins and outs seem to match CO thus supporting this is a process for conversion of carbon monoxide

So which is it, a process to deal with CO₂ or CO?
