Abstract: A center post electrochemical cell stack is disclosed for generating a product gas such as oxygen gas from a supply fluid such as water. The invention could be used to generate oxygen on board a space or aircraft and includes: a frame having a base plate (14) and a wall (16) affixed to the base plate so that the wall and base plate define a cell chamber (18) for housing at least one electrochemical cell; and a T-cap having a top plate (24) and a centeer post (26) affixed to and projecting away from the top plate, wherein the top plate is secured to the wall of the frame to close the cell chamber and the center post passes through a central throughbore in an electrochemical cell within the chamber and is adjustably secured to the base plate of the frame. Consequently, the T-cap and frame cooperate to contain pressure generated by operation of the electrochemical cell. In a specific embodiment of the center post electrochemical cell stack, an exterior surface of the center post of the T-cap cooperates with a central throughbore vented electrochemical cell to define a high pressure manifold (34) for venting of the product gas out of the cell, and an interior surface (36) of the wall of the frame cooperates with the vented central throughbore cell to define a low pressure manifold (40) for transmission of the supply fluid into and out of the cell.
