Abstract
Abstract A porous plate condenser-separator is disclosed providing means of removing water vapor from a fuel cell anode effluent stream. Water vapor condenses on a porous plate and is forced through the plate by virtue of an applied pressure differential. The condensed or liquified water escapes through a relief valve into a reservoir container. This device is useful in a zero gravity environment since water vapor condenses on the porous plate surface and is forced through the plate by gas pressure.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
179 words
A porous plate condenser-separator for removal of water vapor from a mixture of a gas and water vapor, the condenser-separator comprising adjacent chambers having a dividing wall in the form of a porous plate, cooling means for one chamber, means for supplying a coolant to said cooling means, a temperature sensor cooperating with the means for supplying the coolant to said cooling means for maintaining the porous plate at an essentially constant temperature, the chamber having the cooling means being filled with water, means for supplying a gas and water mixture to the other chamber for condensation of the water vapor on the porous plate, the porosity of the plate being such that the pressures in the chambers will cause the condensed water to flow through the plate but will not permit the flow of gas therethrough by reason of the surface tension of the water, and means for removing water from the chamber having the cooling means said means for removing the condensed water including a relief valve set to maintain a preselected pressure value within the chamber.
Claim 2
Dependent Claim
179 words

Claim 3
Dependent Claim
19 words
A condenser-separator as in claim 1, wherein water vapor is removed from a mixture of hydrogen and water vapor.
