NOVELTY - A gas liquid separator comprises an initial baffle and a subsequent baffle arranged within a vessel, between a fluid inlet and a vapor outlet. The initial and subsequent baffles comprise openings providing fluid communication from a fluid inlet side to a baffle vapor outlet side of the initial baffle and the subsequent baffle.    USE - Used for separating gas phase from liquid phase, and in gas generating system (claimed).    ADVANTAGE - The separator is capable of providing completely dry product hydrogen gas in order to reduce the required power inputs to ancillary drying apparatuses.    DETAILED DESCRIPTION - A gas liquid separator comprises a vessel having a fluid inlet, a liquid outlet, vapor outlet and vessel cross-sectional geometry; an initial baffle and a subsequent baffle arranged within the vessel, between the fluid inlet and the vapor outlet, and having a baffle geometry similar to the vessel cross-sectional geometry, where the initial and subsequent baffles comprise openings providing fluid communication from a fluid inlet side to a baffle vapor outlet side of the initial baffle and the subsequent baffle; and a solid plate disposed between the initial baffle and the vapor outlet, where the vapor outlet is in gaseous communication with a side of the solid plate opposite the vapor outlet.    INDEPENDENT CLAIMS are also included for the following:    (a) a gas generating system comprising an electrochemical cell, and a gas/liquid phase separator in fluid communication with the electrochemical cell; and    (b) separating a gas phase from a liquid phase comprising, introducing a stream to a gas/liquid separator; passing an initial portion of the stream through an initial baffle; passing a subsequent portion of the stream through subsequent baffle, where vapor and liquid are separated from the steam; and removing the vapor from the separator.    DESCRIPTION OF DRAWING(S) - The figure is a schematic representation of a gas generating apparatus into which an electrolysis cell system may be incorporated.
