Abstract
An electrochemical oxygen pump moves or pumps oxygen molecules with a unique anion conducting layer comprising an anion conducting polymer. These pumps can either be used as high precision oxygen flow meters or as oxygen filters. The system can be plumbed to have air as the inlet and the pump will selectively pump oxygen out, offering another way to remove oxygen from the air, along with distillation or pressure swing absorption.
