Abstract
Provided are devices, and methods for use with devices, that generate oxygen from residual humidity within a sealed enclosure that is filled primarily with an inert gas. A PEM electrolyzer that is configured to generate oxygen from residual humidity is situated within the sealed enclosure. The PEM electrolyzer includes a PE membrane disposed between an anode and a cathode, and further includes a hydrogen getter. The hydrogen getter helps the PEM electrolyzer to be a net producer of oxygen. Exemplary sealed enclosure devices include hard disk drives such as HAMR hard drives filled primarily with helium.
