Title (EN) LAMINAR FLOW FUEL CELL INCORPORATING CONCENTRATED LIQUID OXIDANT
(FR) PILE À COMBUSTIBLE À ÉCOULEMENT LAMINAIRE INCORPORANT UN OXYDANT LIQUIDE CONCENTRÉ
Abstract:
(EN) Electrochemical cell system. The system includes a low Reynolds number microfluidic channel including spaced apart anode and cathode forming sides thereof. A fuel channel introduces a liquid fuel into the microfluidic channel for laminar flow along the anode and an oxidant channel introduces a concentrated liquid oxidant into the microfluidic channel for laminar flow along the cathode. An electrolyte channel introduces a liquid electrolyte into the microfluidic channel for laminar flow between the fuel and oxidant flows. Electrodes are connected to the anode and cathode for connection to an external load, In another embodiment, the anode is porous and a gaseous fuel such as hydrogen diffuses through the anode into the interior of the microfluidic channel.
(FR) L'invention porte sur un système pile électrochimique. Le système comprend un canal microfluidique de faible nombre de Reynolds comprenant une anode et une cathode à distance l'une de l'autre formant des côtés de celui-ci. Un canal de combustible introduit un combustible liquide dans le canal microfluidique pour qu'il circule de façon laminaire le long de l'anode et un canal d'oxydant introduit un oxydant liquide concentré dans le canal microfluidique pour qu'il circule de façon laminaire le long de la cathode. Un canal d'électrolyte introduit un électrolyte liquide dans le canal microfluidique pour qu'il circule de façon laminaire entre les circulations de combustible et d'oxydant. Des électrodes sont connectées à l'anode et à la cathode pour connexion à une charge externe. Dans un autre mode de réalisation, l'anode est poreuse et un combustible gazeux tel que de l'hydrogène diffuse à travers l'anode vers l'intérieur du canal microfluidique.
