摘要： A layered structure for a fuel cell comprises a carbon-based catalyst-free gas diffusion layer substrate and a carbon-based microporous layer, which is joined to the gas diffusion layer substrate and comprises a plurality of carbon carriers or carbon fibers embedded into an ion-conducting polymer binder mixture. The polymer binder mixture comprises a sulfur-free binding polymer and a sulfonated polymer, and a fraction of the binding polymer at or near a surface of the microporous layer facing away from the gas diffusion layer substrate is less than or equal to a fraction of the sulfonated polymer. A method for producing a layered structure of this type is also provided.

摘要： The invention relates to a cell plate assembly for adjoining an anode side of a membrane electrode assembly of a solid-state compressor, including adjacent first and second cell plates, each having a channel structure incorporated therein. The second cell plate includes a number of passages typically connecting the therein incorporated channel structure with the anode side of the membrane electrode assembly. The channels of the respective channel structures are interconnected at the interfacing surfaces of the first and second cell plates, wherein the channels incorporated in the second cell plate enclose an angle with the channels incorporated in the first cell plate. The invention further relates to a solid-state compressor including a cell plate assembly according to the invention and a method for operating such a solid-state compressor.

摘要： Disclosed herein is a redox flow battery (RFB). The battery generally includes: a positive electrolyte that is a first metal ion, a negative electrolyte that is a second metal ion, an ion exchange membrane positioned between the positive electrolyte and the negative electrolyte. The membrane is configured to restrict and/or prevent the passage of the first metal ion and/or the second metal ion therethrough, and is configured to maintain ionic conductivity between the positive electrolyte and the negative electrolyte.

摘要： Methods useful for the manufacturing of microfluidic cells useful in electronics and other applications are disclosed. In this technique, an air cushioned pressure supplies the force to bond a membrane, which can be made from one or more of the sulfonated tetrafluoroethylene polymers commercially known as Nafion™ (i.e., proton exchange membranes) or from other thermoplastic substrates. A substrate is compressed and templated while it is simultaneously sealed inside the cell. The resultant microcells are strongly sealed while being patterned according to their application.
