Abstract (en)
[origin: WO0227813A2] 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.
