摘要： A flow-through redox galvanic cell and a battery is described, where each flow-through galvanic cell is separated into two parts by a metal foil serving as a bi-electrode in contact with two solutions having different redox potentials. Voltage due to redox processes is formed through the foil, and two traditional electrodes (cathode and anode) in each cell are not necessary anymore. The cells in a battery should be in electric contact with each other via ion-selective membranes. The battery is easy to recharge, and it is smaller, lighter, safer and cheaper than known redox-flow batteries. It may be used as a reserve source of energy in electric grids and households. It also may be used in electric cars, and it is especially attractive for use near the seashore and on sea ships.

摘要： Various embodiments of the present disclosure provide a fuel cell tube including one or more laterally segmented fuel cells each including multiple fuel cell portions that are electrically isolated from one another. When assembled into a fuel cell stack, secondary interconnects electrically connect adjacent fuel cell tubes via their respective laterally segmented fuel cells. The use of laterally segmented fuel cells to effect the fuel cell tube-to-fuel cell tube electrical connection enables more accurate testing of the electrical connection between adjacent fuel cell tubes.

摘要： A ceramic substrate for an electrochemical element that includes a ceramic layer and a high-thermal-expansion-coefficient material layer that is laminated on the surface of the ceramic layer. The high-thermal-expansion-coefficient material layer has a higher coefficient of thermal expansion than the ceramic layer, and applies compressive stress to the ceramic layer.

摘要： A method for coating a separator for a fuel cell is provided that includes vaporizing a metal carbide precursor to obtain a precursor gas; introducing a metal carbide coating layer-forming gas including the precursor gas in a reaction chamber; and applying a voltage to the reaction chamber so that the precursor gas is changed into a plasma state, thereby forming a metal carbide coating layer on either surface or both surfaces of a substrate. In this case, the metal carbide precursor may include a compound having a substituted or non-substituted cyclopentadienyl group.
