Methods for assembling an electrochemical cell
A method for securing an anode, a cathode and an ion exchange membrane disposed between the anode and the cathode within a premolded thermoplastic frame. The frame both secures the anode the cathode and the ion exchange membrane within the frame and further maintain the anode, cathode and membrane in intimate contact. Additionally, injection molding around the premolded thermoplastic frame may be performed or alternatively, injection molding around a plurality of thermoplastic frames.
1. A method of making an electrochemical cell comprising:
securing an anode, a cathode and an ion exchange membrane disposed between the anode and the cathode between opposing members of a premolded thermoplastic frame, wherein the thermoplastic frame maintains the anode, the cathode, and the membrane in intimate contact,
wherein the step of securing further comprises securing the opposing members face to face without a separator plate.
2. The method of claim 1 , wherein the step of securing the opposing members face to face comprises:
injection molding around the premolded thermoplastic frame.
3. The method of claim 1 , wherein the step of securing the opposing members face to face comprises:
injection molding around a plurality of premolded thermoplastic frames.
4. The method of claim 1 , wherein the step of securing the opposing members face to face comprises:
clamping the opposing members of the frame.
5. The method of claim 1 , wherein the step of securing the opposing members face to face comprises:
latching the opposing members of the frame.
6. The method of claim 1 , wherein the step of securing the opposing members face to face comprises:
threadedly securing the opposing members of the frame.
7. The method of claim 2 , wherein the step of injection molding around the premolded frame comprises:
forming a housing around at least a perimeter of the frame.
8. The method of claim 2 , wherein the step of injection molding around the premolded frame comprises:
forming a housing around the frame, wherein the housing comprises an anode reservoir in fluid communication with the anode arid a cathode reservoir in fluid communication with the cathode.
9. The method of claim 8 , further comprising:
forming a means for securing the housing to an associated system.
10. The method of claim 2 , further comprising:
preventing molten thermoplastic from contacting an active area of the cathode and the anode during the step of injection molding around the assembly.
