Title:
ELECTROLYTE CIRCULATION TYPE STACKED CELL
Document Type and Number:
Japanese Patent JPS6321763
Kind Code:
A
Abstract:

PURPOSE: To increase the efficiency and life of a cell by forming the frames or frame of a frame-installed electrode and/or a frame-installed membrane with ionomer resin.

CONSTITUTION: A membrane frame 5a of an MC frame-installed membrane 5 and an electrode frame 6a of a plate frame-installed middle electrode 6 are formed with ionomer resin, and the membranes 5 and the electrodes 6 are alternately stacked. The frame material of the electrode 6 and the membrane 5 has a bending elastic modules of 3000kg/cm2 or less and a volume resistivity of 1014Ω or more. Liquid passage 16 is formed in the electrode frame 6a and/or the membrane frame 5a, and continuous ribs are installed in the surroundings of the liquid passage 16 and an electrode 12, and the the ribs concentrically receive the fastening pressure of the stack to ensure seal. Close adhesion of the contact surface can surely be obtained by only the contact of frame-to-frame, and plastic deformation of the frame material can be prevented. Therefore, the efficiency and life of a cell are increased.
