摘要： A metal-air cell has a first housing part and a second housing part that together form a cell housing. The metal-air cell includes a metal based anode and a layer-shaped air cathode and an electrolyte. The first housing part has at least one air passage opening. A layer-shaped air diffusor is disposed between the first housing part and the air cathode. A layer-shaped separator is arranged between the air cathode and the metal based anode. The layer-shaped air diffuser is air-permeable and has a first side facing the air cathode and a second side facing away from the air cathode, wherein the layer-shaped air diffuser has a hydrophobic coating on at least one of the sides.

摘要： Electrochemical reactors with electrodes that have variable porosity across the electrode and associated methods are described. The electrodes are designed and micro-architected to have variable porosity and 3D flow. One example method of selecting porosities in an electrochemical reactor includes dividing an electrode of the electrochemical reactor into a plurality of unit cells and determining a plurality of cell-specific porosities for the plurality of unit cells as a function of a location for each of the plurality of unit cells. The cell-specific porosities are configured based on a rod diameter of each unit cell's internal structure relative to each unit cell's cell length, and each location in the electrode provides a selected fluid flow property and a selected conductive property to meet one or more performance metrics.

摘要： A membrane electrode assembly includes: a polymer electrolyte membrane; a pair of electrode catalyst layers disposed with the polymer electrolyte membrane therebetween while being in contact with a surface of the polymer electrolyte membrane; and a gas diffusion layer laminated on each of the pair of electrode catalyst layers. The gas diffusion layer includes a microporous layer in contact with the electrode catalyst layer and a diffusion substrate layer made of a fiber substrate. An average fiber diameter of a fiber material contained in the diffusion substrate layer is 10 times or more and 150 times of less of an average fiber diameter of the fibrous substance contained in the electrode catalyst layer.

摘要： A technique may produce a composite at a low temperature by a reducing agent that is easy to handle. A technique may produce a composite in which a metal simple substance or a metal oxide derived from reduced cations, or both of them are supported on a carrier. The technique may include at least: preparing a liquid phase mixture containing at least an alcohol compound as a first reducing agent, a phosphinic acid or a salt thereof as a second reducing agent, the carrier, and a source compound of one or more cations selected including Au, Ag, Cu, Pt, Rh, Ru, Re, Pd, and/or Ir; and reducing the cations in the liquid phase mixture.
