ABSTRACT:
An electrochemical cell, comprises (a) a first electrode, (b) a second electrode, (c) a first fluid, in contact with the first electrode, and (d) a second fluid, in contact with the second electrode. The first fluid and the second fluid are in parallel laminar flow, and the first fluid has a pH different from the second fluid.
