[Also in Division H1] Water is removed from the electrolyte of a fuel cell battery by passing it through chamber 28 bounded by asbestos diaphragm 27', while cold water flows through chamber 30 bounded by asbestos diaphragm 27. The middle chamber 32 is connected to one of the gas-feed spaces of the battery, and is at an excess pressure of 0.2 atmosphere with respect to the flow of electrolyte. Water evaporates from diaphragm 27' and condenses in diaphragm 27.
