Abstract

A water separation cell for removing the reaction water from the electrolyte of fuel cells and fuel cell batteries which comprise a liquid chamber bounded on at least one side by a porous diaphragm, and a gas chamber bounded by the diaphragm and a condensation surface adapted for cooling, in which the liquid chamber is subdivided into two chambers of different size which are arranged on top of each other with the upper, larger chamber serving as the electrolyte space and the lower, smaller chamber taking up the condensate which passes through the porous diaphragm into this chamber due to the pressure of a gas present in the gas chamber.
