Abstract:
1. A compression sealable electrolysis cell assembly comprising: two electrode tubes of different diameters, each electrode tube having an electrical connector; a ceramic membrane tube situated around said inner diameter electrode tube and within said outer diameter electrode tube wherein said tubes are parallel to a central axis of the assembly; two insulating end pieces, each of said pieces comprising at least one hole extending on or parallel to said central axis and three concentric seats with diameters for positioning said tubes; at least one seal forming features in the vicinity of each of said seats, wherein said electrode tubes comprise a seal formed by said feature positioned between said seat and an end of said electrode tube or positioned on a surface of said end piece parallel to said electrode tube and said electrode tube, and wherein said ceramic membrane tube comprises a seal formed by said feature positioned on a surface of said end piece or said electrode tubes parallel to said ceramic membrane tube; two pairs of ports for entrance or exit of fluid, each comprising an external fitting for attachment of a hose or pipe, wherein said first pair of ports at opposite ends of said assembly internally addresses a space between said outer electrode tube and said membrane and said second pair of ports at opposite ends of said assembly internally addresses a space between said inner electrode tube and said membrane; at least one rod with at least one threaded end, each rod inserted through said holes in both of said end pieces with a nut on each of said threaded ends, wherein compression and sealing of said electrolysis cell assembly results upon tightening said nuts on said threaded ends and wherein upon sealing of said electrolysis cell assembly the distance between said seats for positioning said ceramic membrane tube is greater than the length of said ceramic membrane tube, whereby no compressive force is imposed upon said ceramic membrane tube by said seats.
