METHOD AND ELECTROCHEMICAL CELL FOR MANAGING ELECTROCHEMICAL REACTIONS

摘要

A method and/or electrochemical cell for utilising one or more gas diffusion 5 electrodes (GDEs) in an electrochemical cell, the one or more gas diffusion electrodes have a wetting pressure and/or a bubble point exceeding 0.2 bar. The one or more gas diffusion electrodes can be subjected to a pressure differential between a liquid side and a gas side. A pressure on the liquid side of the GDE over the gas side does not exceed the wetting pressure of the GDE during 10 operation (in cases where a liquid electrolyte side has higher pressure), and/or a pressure on the gas side of the GDE over the liquid side, does not exceeds the bubble point of the GDE (in cases where the gas side has the higher pressure).

1. A method for managing an electrochemical reaction in an electrochemical cell, the electrochemical cell having a gas diffusion electrode positioned between a liquid electrolyte and a gas region, the method comprising:
applying a pressure differential between the liquid electrolyte and the gas region that is less than a wetting pressure or a bubble point of the gas diffusion electrode relative to the liquid electrolyte and a gas used or consumed in operation of the cell; wherein the wetting pressure or the bubble point is greater than 0.2 bar.
