Abstract: An improved electrochemical energy storing device includes a number of thin-film electrochemical cells which are maintained in a state of compression through use of an internal or an external pressure apparatus. A thermal conductor, which is connected to at least one of the positive or negative contacts of each electrochemical cell, conducts current into and out of the electrochemical cells and also conducts thermal energy between the electrochemical cells and thermally conductive material disposed on a wall structure adjacent the conductors. The wall structure includes electrically resistive material, such as an anodized coating or a thin film of plastic. The thermal conductors are fabricated to include a spring mechanism which expands and contacts to maintain mechanical contact between the electrochemical cells and the thermally conductive material in the presence of relative movement between the electrochemical cells and the wall structure. An active cooling apparatus may be employed external to a hermetically sealed housing containing the electrochemical cells to enhance the transfer of thermal energy into and out of the electrochemical cells. An integrated interconnect board may be disposed within the housing onto which a number of electrical and electro-mechanical components are mounted. Heat generated by the components is conducted from the interconnect board to the housing using the thermal conductors.

Patent CA-2306265-C (CA)
Inventor: TRIVETT D ANDREW
IPC: B01D47/02
Filed: 1998-10-07
Granted: 2008-12-02
Abstract: An exhaust gas scrubber including a tank of scrubbing liquid into which a downcomer pipe(s) feeds inlet gas and fresh scrubbing liquid from a plenum. The inlet gas flows through slotted vortex generators forming fine-scale bubbles encapsulated within a scrubbing liquid. The bubbles mix and coalesce in a turbulent motion, and are then passed through another set of vortex generators which break up coalesced bubbles and form fresh fine sized bubbles, and impart an angular velocity to the mixture. Formation and coalescence of the bubbles produce gas phase to liquid phase mixing and scrubbing. Centrifugal forces created through the slotted vortex generator produce liquid circulation and recycle. The bubbly mixture then rises, bubbles coalesce and break, and the liquid scrubbing solution falls back, flowing into a relatively quiescent down flow zone around the perimeter of the scrubber outside of an overflow weir or weirs.  The outlet gas rises into a freeboard section where de-mister and heat exchanger pipes remove scrubbing vapour from the outlet gas. The scrubbing liquid flows downward into a quiescent settling tank where honeycomb vortex breakers inhibit turbulence to ensure settling of particulate into the sediment. Internal solids separation is accomplished in quiescent zones between the outer walls of the overflow dam(s) and the inner walls of the housing, and below the honeycomb vortex inhibitors. A conical bottom to the tank permits the settling sediment to be flushed out of the scrubber with the outlet scrubbing liquid. Scrubber solution liquid level is controlled by a flow and level control valving arrangement. Scrubber solution temperature is controlled by a complementary arrangement of flow controls.
