ABSTRACT:
A distributing element for an electrolyte percolating-type electrochemical cell comprises an external feeding manifold and an assembly formed by a gas diffusion electrode, a percolator and optionally an on-exchange membrane. The element is particularly suitable for chlor-alkali electrolysis cells and alkaline fuel cells. It is also disclosed a method for retrofitting membrane electrochemical cells by inserting the distributing element of the invention therein.
