"coated fuel/electrolysis cell cathode with lithium oxide... adding small amount lithium... recover initial performance of poisoned cell... added more lithium, performance... improvements three to four orders of magnitude in key oxygen reduction reaction rate and... populating the surface of the electrode with electrons needed to drive the oxygen incorporation reaction... lithium oxide effectively dissolves the chromium to form a glassy material that no longer serves to degrade the cathode performance"
