摘要： A method for the preparation of a gas diffusion layer, containing the steps of: a) preparing a carrier-binder paste comprising a solvent, a fluorinated binder and conductive carrier articles; b) preparing an adhesive composition comprising a solvent, a fluorinated binder and essentially no or equal to or less than 15 wt. % of conductive carrier particles, based on the total weight of fluorinated binder and any conductive carrier particles; and c) combining a layer of supporting material, a layer of the adhesive composition and a layer of the carrier-binder paste, wherein the layer of the adhesive composition is applied between the layer of supporting material and the layer of the carrier-binder paste, and pressing the combination of supporting material, adhesive composition and carrier-binder paste at a pressure of at least 15 kilopascal and/or heating the combination of supporting material, adhesive composition and carrier-binder paste at a temperature of at least 300° C., and a gas diffusion layer so prepared.

摘要： The invention concerns a process for the electrochemical production of formate. The process is performed in an electrochemical cell comprising a cathode compartment containing a cathode, an anode compartment containing a nickel-based anode and an ion exchange membrane separating the anode compartment from the cathode compartment. The process comprises the following steps: (a) feeding an anolyte comprising at least one polyol to the anode compartment; (b) feeding a catholyte comprising CO2 to the cathode compartment; (c) and applying a voltage difference between the cathode and the anode such that at the cathode CO2 is reduced to formate and at the anode the at least one polyol is oxidized to formate.

摘要： Electrochemical conversion of CO2 to formic acid or a salt thereof, using an indium containing catalytic electrode, comprising (a) electrochemically converting CO2 to formic acid or a salt thereof by applying a voltage to an electrochemical cell comprising the catalytic electrode as cathode and an anode, wherein the electrochemical cell is fed with an electrolyte comprising CO2; and (b) regenerating the catalytic electrode by lowering the voltage and subsequently washing the catalytic electrode with an aqueous liquid and exposing the catalytic electrode to air without applying voltage; and (c) optionally repeating steps (a) and (b).
