An electrochemical cell includes a first electrode, a second electrode, a proton exchange membrane disposed between and in intimate contact with the electrodes, and a pressure pad disposed in electrical communication with the first electrode. The pressure pad is an electrically conductive sheet and is of a structure that is conformable to pressure variations within the cell. Methods of forming the pressure pad include disposing dimples or corrugations at the electrically conductive member. A method of maintaining compression within the cell includes disposing the electrically conductive member and the compression member at the first electrode, applying a load at the cell to compress the cell components, and maintaining electrical communication through the electrically conductive member.

Apparatus and method for maintaining compression of the active area in an electrochemical cell

A gas/liquid phase separator for an electrolysis cell includes a vessel and a float in operable communication with each other. The vessel includes a fluid inlet and first and second fluid outlets. A fluid stream comprising gas and liquid is received in the vessel through the fluid inlet, and at least a portion of the gas exits the vessel through the second fluid outlet. The float is configured to interface with the first fluid outlet and either maintain or prevent fluid communication across the first fluid outlet when the float is in at least partial contact with the first fluid outlet.

A reactant source for an electrolysis cell includes a vessel configured to contain water, a funnel disposed in integrated communication with the vessel, and a door disposed over the funnel. The door may be slidably or pivotally mounted over the funnel and is configured to prevent the introduction of an object into the funnel.

The present invention is an integrated screen comprising a screen portion having openings and an integral protector edge disposed about the periphery of the screen portion. This integrated screen protector edge can be utilized individually as the membrane support/flow field in an electrochemical cell or in conjunction with one or more subsequent screen layers. When utilized with subsequent screen layers, the integrated screen protector edge is disposed adjacent to and in intimate contact with the membrane assembly.

The present invention relates to a unique, compact hydrogen electrochemical system which eliminates the need for explosion-proof equipment. This system merely separates the electrical equipment from the hydrogen source with a wall, but employs a positive pressure, of about 0.1 inches water column, air purge throughout the system to prevent the introduction of hydrogen gas to the electrical equipment and to recover and use waste heat.
