Abstract
Method of removing reaction water from a fuel cell includes bringing electrolyte of the fuel cell in contact with a diaphragm having a given capillary depression pressure and permeable to water vapor so that water vapor contained in the electrolyte diffuses through the diaphragm into a chamber containing a gas at a given pressure, and passing the diffused water vapor to a location at which it engages with a cooled condensation surface and condenses thereon, the electrolyte having a hydrostatic pressure equilibrated by at least one of the pressures exerted by the gas and the capillary depression in the diaphragm. Apparatus for carrying out the foregoing method includes a gas chamber, a chamber for electrolyte, means separating said chambers from one another comprising a diaphragm permeable to water vapor contained in the electrolyte, a condensation surface located in the gas chamber for condensing water vapor coming in contact therewith, and means connected to the gas chamber for discharging therefrom water condensed by the condensation surface.
