Claims
- 1. An electrochemical cell comprised of:
- a plurality of first polarity electrodes and a plurality of second polarity electrodes alternately arranged in a battery stack; and
- a plurality of porous coupling members made of porous metal positioned between and in contact with the facing surfaces of adjacent first polarity electrodes thereby providing meachanical and electrical coupling between said first polarity electrodes while allowing liquid communication with said electrodes.
- 2. The electrochemical cell of claim 1 wherein said coupling members are welded together.
- 3. The electrochemical cell of claim 1 wherein 5% to 20% of the volume of said coupling member is metal, and 95% to 80% of the volume consists of pores permeating said metal.
- 4. The electrochemical cell of claim 3 wherein the size of said pores is about in the range of 20 mils to 50 mils and said metal is nickel.
- 5. The electrochemical cell of claim 3 wherein the size of said pores is in the range of 20 mils to 50 mils and said metal is nickel chromium.
