Abstract
The invention disclosed herein relates to fuel cell electrode pair assemblies, not having interposing proton exchange membranes, configured to receive and react with liquid anolyte and liquid catholyte microfluidic flowstreams. In one embodiment, the present invention is directed to a fuel cell electrode pair assembly, not having an interposing proton exchange membrane, configured to receive and react with a liquid microfluidic anolyte flowstream (e.g., laminarly flowing methanol solution) and a liquid microfluidic catholyte flowstream (e.g., laminarly flowing nitric acid solution), wherein the fuel cell electrode pair assembly comprises: a porous flow-through anode; a porous flow-by cathode confronting and spaced apart from the anode; and a central plenum interposed between and connected to the anode and the cathode.
