Abstract
An electrochemical cell having a hydraulically impermeable permselective membrane located between electrodes comprising at least one gas diffusion, laminar electrode having hydrophilic and hydrophobic layers and attendant current collector means is operated with greater efficiency by forcing the laminar, gas diffusion electrode against the current collector means so as to make and maintain electrical contact therebetween by means of gas pressure exerted against the hydrophobic side of the laminar, gas diffusion electrode opposite to that which faces the permselective membrane.
