Abstract
The invention disclosed herein relates to fuel cell and electrochemical cells having internal multistream laminar flow and, more specifically, to microfluidic fuel cell and electrochemical cells having two or more adjacent and cross-flowing (i.e., non-parallel) laminar flowstreams positioned within an electrode pair assembly. In one embodiment, an electrochemical cell is disclosed that comprises: a first electrode; a second electrode that opposes the first electrode; and a channel or plenum interposed between and contiguous with at least a portion of the first and second electrodes. The electrochemical cell of this embodiment is configured such that a first fluid enters the channel or plenum and laminarly flows adjacent to the first electrode in a first flow direction, and a second fluid enters the channel or plenum and laminarly flows adjacent to the second electrode in a second flow direction, wherein the first and second flow directions are different from each other.
