Abstract: An electrochemical cell frame for an electrolysis application utilizing an electrochemical cell is provided. The electrochemical cell frame can include a frame body, an internal sealing member, and an external sealing member. The frame body can be formed from a polymer material. The frame can define an active area, a flow passage, and a port. The active area can be configured to accommodate the electrochemical cell. The flow passage can be configured to direct fluid flow into or out of the active area. The port can be fluidly connected to the flow passage. The internal sealing member can be integrally formed with the frame body and positioned to separate fluid streams within the electrochemical cell. The external sealing member can be integrally formed with the frame body and positioned to militate against fluid leakage from the electrochemical cell.

Abstract: A membrane is provided that includes a membrane substrate defining a plurality of pores to allow ion transport therethrough; an ion-doped conductive polymer disposed on a surface of the membrane substrate; and a conductive material disposed between the membrane substrate and the ion-doped conductive polymer. The membrane may have an areal density from about 0.01 Coulombs per cm2 (C/cm2) to about 100 C/cm2. Such membranes provide for controlled bidirectional ion transport therethrough and may be used in electrochemical cells that includes such membranes as part of (or the entirety of) the separator. Such separators may be used to control charge transfer through the electrochemical cell and/or reversibly stop charge transfer therethrough to prevent thermal runaway.
