Maget, H J.R.

This patent describes a planar multi-junction electrochemical pump for pumping an electrochemically active fluid, the pump comprising: a container defining an inlet chamber in a first portion thereof and an outlet chamber in a second portion thereof; a single electrolytic membrane disposed within the container between the chambers and forming therebetween a gas-tight seal; a plurality of pairs of electrodes disposed on either side of and in contact with the electrolytic membrane, the electrodes in the inlet chamber being separated from one another by spaces and the electrodes in the outlet chamber being separated from one another by spaces; means for electrically connecting the electrodes; and means for applying an electrical voltage to the electrodes to establish a voltage gradient across the membrane to convert the fluid into ions in the inlet chamber, propel the ions through the membrane into the outer chamber, and reconvert the ions into fluid in the outlet chamber whereby the fluid is pumped from the inlet chamber into the outlet chamber.
