Abstract:
1. A fuel cell structure useful for providing laminar flow regimes in a plurality of fluids flowing in mutual contact in a laminar flow channel, comprising: a laminar flow channel defined within said fuel cell structure; at least two entrance apertures defined within said fuel cell structure, a first entrance aperture configured to admit a first fluid into said laminar flow channel and a second entrance aperture configured to admit a second fluid flow into said laminar flow channel, said first entrance aperture and said second entrance aperture configured to provide respective entry of said first fluid flow and said second fluid flow parallel to each other prior to the laminar flow channel; a flow control structure situated adjacent said at least two entrance apertures for admitting said fluid flows into said laminar flow channel, said flow control structure configured to cause each of said fluid flows to flow in a laminar flow regime within said laminar flow channel; at least one exit aperture defined within said fuel cell structure for permitting said fluids to exit said laminar flow channel; a first diffuser/condenser structure having a first inlet though which the first fluid enters from a first external source and a first outlet from which the first fluid exits into a laminar flow channel; and a second diffuser/condenser structure having a second inlet through which the second fluid enters from a second external source and a second outlet from which the second fluid exits into a laminar flow channel; wherein said fuel cell structure is configured to provide laminar flow regimes in two fluids flowing in mutual contact in said laminar flow channel and wherein the first and second inlets and first and second outlets respectively have substantially different cross-sectional dimensions and further wherein the width of the first and second outlets are equal to each other and to the width of the laminar flow channel, both as measured parallel to the interface between the first and second fluids at the laminar flow channel's first and second entrance apertures.
