The invention relates to a method for electrochemical production of a product in an electrochemical cell comprising an extraction compartment. The extraction compartment comprises a liquid comprising a dissolved polyelectrolyte. The method comprises producing cations at an anode, producing anions at a cathode and transporting the ions through ion- selective membranes into the extraction compartment where the product is formed. The invention further relates to an electrochemical cell for use in the method.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell.

In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

Disclosed is a method for producing a hydrogen-generating fuel, the hydrogen-generating fuel obtained, a method for producing hydrogen from the fuel, a device for carrying out the production method, a method for operating the device, and a hydrogen-based fuel obtained by use of the production method. The production method is characterized in that it consists in mixing, in a liquid, particles of one or more metals which are corrodible by a basic chemical substance or an acidic chemical substance for the purpose of producing hydrogen, the particles being kept in suspension in the liquid, and the mixture composed of the liquid and the particles being chemically stabilized so as to prevent chemical reaction between the liquid and the particles.

Metastable alloys have recently emerged as high-performance catalysts, extending the toolbox of binary alloy materials that can be utilized to mediate electrocatalytic reactions. In particular, nanostructured metastable ordered intermetallic compounds are particularly challenging to synthesize. Here the present invention is directed to a method for synthesizing sub-15 nm metastable ordered intermetallic Pd31Bi12 nanoparticles at room temperature, in a single step, by pulsed electrochemical deposition onto high surface area carbon supports. The resulting Pd31Bi12 nanoparticles displays a 7× enhancement of the mass activity relative to Pt/C and a 4× enhancement relative to Pd/C for the oxygen reduction reaction (ORR). The high performance of Pd31Bi12 nanoparticles is demonstrated to arise from reduced oxygen binding caused by alloying of Pd with Bi. The isolation of Pd-sites from each other facilitate methanol tolerant ORR behavior.
