Abstract: A separator plate and a frame member for an electrochemical cell are provided. The separator plate includes a plurality of protrusions extending therefrom to define a flow field. A pair of end features arranged along opposite sides of the flow field, each end feature extending substantially the length of the flow field. A periphery portion is provided having a first set of openings and a second set of openings. Wherein the plurality of protrusions and pair of end features extend from a plane defined by the periphery portion. The frame member includes features for facilitating assembly and reducing the risk of an over constrained condition. The frame member further having ports divided by a bridge member to support the frame member under operating pressures.

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.

Abstract: A circuit board cooling system employs a closed liquid delivery system to transfer heat from integrated circuits to a cooling liquid. The system includes one or more cooling panels that may be attached to a circuit board. Each cooing panel includes at least one channel for the circulation of cooling liquid stamped into a thermally conductive material. Each panel may include multiple levels in order to conform to the profile of integrated circuits to be cooled.

Abstract: A circuit board cooler employs a closed fluid delivery system to transfer heat from electronic components to a cooling fluid. One or more channels embedded within the circuit board carry cooling fluid to the components where the fluid absorbs heat from the component, then away from the component to deposit the excess thermal energy in a thermal sink, such as a heat exchanger. The cooling system may employ conductive thermal transfer elements, such as “thermal vias”, to enhance heat transfer from electronic components to the cooling fluid.

Abstract: A load counterbalancing system with a constant load displacement force includes a load element, a position transducer and an actuator element. An environmental force acting upon the load element is counterbalanced by a support force provided by the actuator element. The environmental force is assumed to be a predetermined function of the position of the load element, and the actuator element applies the support force to the load element as defined by the predetermined function. The invention allows an operator to move the load element through its entire range of motion with a constant applied force, and to place the load element statically at any position in the range of motion.
