Solid state electrochemical pollution control device

A dry, solid state electrochemical scrubber assembly adapted for use in a gaseous combustion exhaust stream containing noxious components comprising;

• a cell having a high surface area, porous solid electrolyte body, permitting the passage of said exhaust stream therethrough, said body having a first end, a second end, and an outer surface;
• an upstream sealing member in fluid tight communication with said first end of said cell and with an upstream portion of an exhaust conduit;
• a downstream sealing member in fluid tight communication with said second end of said cell and with a downstream portion of said exhaust conduit;
• a first discrete conductive area disposed on a portion of said cell surface;
• a second discrete conductive area disposed on a portion of said cell surface;
• a first electrode connector cooperating with said first discrete conductive area;
• a second electrode connector cooperating with said second discrete conductive area;
• and
• first and second electrodes cooperating with said electrode connectors and an alternating or direct current source.

A solid state electrochemical ceramic cell adapted to alter the composition of a fluid stream containing noxious component passing therethrough comprising:

• a porous, high surface area body having a gas-receiving first end seal portion, a gas egressing second end seal portion and substantially gas impervious side walls defining the length of the cell;
• a high surface area, porous solid electrolyte forming the body of cell interior, permitting the passage of fluid stream therethrough, a first sealable end portion adapted to communicate in fluid tight engagement with an gas stream ingress conduit, a second, spaced-apart end portion adapted to communicate in fluid tight engagement with a gas stream egress conduit, a gas communicating passageway through the cell length extending from the first sealable end portion through the second sealable end portion and adapted to carry gas through the length of the cell;
• a first electronically conductive region and a second electronically conductive region, said regions disposed in electronically opposing segments of the cell;
• a first electrode connection member located in said first conductive region and a second opposing electrode connection member located within said second conductive region;
• said cell end portions adapted to be positioned in gas-tight engagement with conduit means which deliver and remove a gas stream to be treated to and from the cell.
