Abstract: An electrochemical cell includes a mist elimination system that prevents mist from escaping from the cell chamber and conserves moisture within the cell. An exemplary mist elimination system includes a spill prevention device that reduces or prevents an electrolyte from escaping from the cell chamber in the event of an upset, wherein the electrochemical cell is tipped over. A mist elimination system includes a recombination portion that reacts with hydrogen to produce water, that may be reintroduced into the cell chamber. A mist elimination system includes a neutralizer portion that reacts with an electrolyte to bring the pH closer to neutral, as acid/base reaction. A mist elimination system includes a filter that captures mist that may be reintroduced into the cell chamber. A mist elimination system includes a hydrophobic filter on the outer surface to prevent water and other liquids from entering into the mist elimination system.

Abstract: An electrochemical cell utilizes an air flow device that draws air through the cell from a scrubber that may be removed while the system is operating. The negative pressure generated by the air flow device allows ambient air to enter the cell housing when the scrubber is removed, thereby enabling continued operation without the scrubber. A moisture management system passes outflow air from the cell through a humidity exchange module that transfers moisture to the air inflow, thereby increasing the humidity of the air inflow. A recirculation feature comprising a valve allow a controller to recirculate at least a portion of the outflow air back into the inflow air. The system may comprise an inflow bypass conduit and valve that allows the humidified inflow air to pass into the cell inlet without passing through the scrubber. The scrubber may contain reversible or irreversible scrubber media.

Abstract: An example system for molding a photocurable material into a planar object includes a first mold structure having a first mold surface, a second mold structure having a second mold surface, and one or more protrusions disposed along at least one of the first mold surface or the second mold surface. During operation, the system is configured to position the first and second mold structures such that the first and second mold surfaces face each other with the one or more protrusions contacting the opposite mold surface, and a volume having a total thickness variation (TTV) of 500 nm or less is defined between the first and second mold surfaces. The system is further configured to receive the photocurable material in the volume, and direct radiation at the one or more wavelengths into the volume.
