摘要： A method of manufacturing a membrane-electrode assembly including an electrolyte membrane and a catalyst layer-formed gas diffusion layer bonded to the electrolyte membrane, the method including: a liquid application step of applying, in the atmosphere, a liquid to only a surface of the catalyst layer before bonding; and a thermocompression bonding step of bonding, to the electrolyte membrane, the catalyst layer-formed gas diffusion layer to which the liquid is applied, by thermocompression bonding. Provided is a method of manufacturing a membrane-electrode assembly including a polymer electrolyte membrane and a catalyst layer-formed gas diffusion layer bonded to the polymer electrolyte membrane, in which the manufacturing method can achieve both the relaxation of thermocompression bonding conditions and the improvement of adhesion between the catalyst layer-formed gas diffusion layer and the electrolyte membrane with high productivity.

摘要： Disclosed are a manufacturing method of a membrane electrode assembly capable of increasing the interfacial adhesion between a polymer electrolyte membrane and a catalyst layer, improving substance delivery and performance, and enhancing hydrogen permeation resistance or oxygen permeability; a membrane electrode assembly manufactured thereby; and a fuel cell comprising the membrane electrode assembly. The manufacturing method of the present invention comprises the steps of: adding a catalyst and a first ionomer to a solvent and dispersing the same, thereby producing a dispersed mixture; adding a second ionomer to the dispersed mixture, thereby producing a coating composition; and applying the coating composition directly onto at least one side of the polymer electrolyte membrane.

摘要： A method of producing electrodes includes selecting a palladium alloy, annealing the palladium alloy at a first temperature above 350° C., cold working the palladium alloy into a desired electrode shape, and annealing the palladium alloy at a second temperatures and for a time sufficient to produce a grain size between about 5 microns and about 100 microns. The method further includes etching the palladium alloy, rinsing the palladium alloy with at least one of water and heavy water, and storing the palladium alloy in an inert environment.

摘要： Disclosed are anode electrode structures for microbial fuel cell (MFC) devices, systems and methods for treating wastewater and generating electrical energy through a bioelectrochemical waste-to-energy conversion process. In some aspects, an anode electrode includes a conductive core and a plurality of sheets of conductive textile material wound around the conductive core. In some aspects, the anode electrode is produced by cutting sheets of a conductive textile material to form a stem and a plurality of branches connected to the stem. The conductive textile material is pretreated to enhance the surface area, hydrophilicity, microbial attachment, and/or electrochemical activity of the conductive textile material. The sheets are stacked together and wound around a conductive core to produce the anode electrode. In implementations, the anode electrode can be used to transfer electrons removed from wastewater surrounding the branched electrode via an oxidation reaction on the electrode surface within the an MFC device.
