Embodiment Construction

[0020] Embodiments of the present invention provide the advantage of allowing the thickness of the electrochemical cell membrane to be varied without affecting the reaction volume on either the anode side or the cathode side of the electrochemical cell. Still other embodiments of the present invention enable the use of framing members to seal the interface of the MEA without compromising the integrity of the membrane. Yet other embodiments provide the advantage of allowing the same frame member to be used on both the anode side and the cathode side of the electrochemical cell.

[0021] First refer to figure 2 , an exemplary electrochemical cell 200 that may be adapted to operate as an anode-fed electrolysis cell, a cathode-fed electrolysis cell, a fuel cell, or a regenerative fuel cell is depicted in an exploded assembly isometric view. Thus, while the discussion below may be directed to anode-fed electrolysis cells, cathode-fed electrolysis cells, fuel cells, and regenerati...

Abstract

An electrochemical cell is provided. The electrochemical cell includes a first frame, the frame having at least one first cleat feature arranged on one side, the at least one first cleat feature having a first height. A second frame is provided having at least one second cleat feature arranged on one side, the at least one second cleat feature having a second height. A membrane electrode assembly (MEA) is disposed between the first and second frame, the MEA having a first electrode disposed on a first side of a membrane and a second electrode disposed on a second side opposite the first electrode. A first gasket is disposed between the membrane and the first frame, the first gasket engaging the at least one first cleat feature. A second gasket is disposed between the membrane and the second frame, the second gasket engaging the at least one second cleat feature.

Description

Background technique [0001] The subject matter disclosed herein relates to electrochemical cells, and in particular, to electrochemical cells having a gasket disposed as a protective membrane and sealing the cell to prevent fluid leakage. [0002] Electrochemical cells are energy conversion devices, generally classified as electrolysis cells or fuel cells, including, but not limited to, electrolysis cells with a hydrogen-water supply. The proton exchange membrane electrolyzer acts as a hydrogen generator by electrolyzing water to produce hydrogen and oxygen. refer to figure 1 , in a typical single anode fed water electrolysis cell 101 , process water 102 reacts at an oxygen electrode (anode) 103 to form oxygen 104 , electrons, and hydrogen ions (protons) 105 . The reaction is performed by electrically connecting the positive terminal of the power source 106 to the anode 103 , and the negative terminal of the power source 106 to the hydrogen electrode (cathode) 107 . Oxygen ...
