The redox flow secondary battery includes an electrolytic cell including a positive electrode cell, a negative electrode cell, and a separation membrane that separates the positive electrode cell and the negative electrode cell. Moreover, the above described redox flow secondary battery is configured as follows. That is, the separation membrane has a microporous membrane and an ion-exchange resin layer contacting the microporous membrane, and the air resistance of the separation membrane per thickness of 200 μm is 10000 sec/100 cc or more. Furthermore, the microporous membrane includes a polyolefin resin or a vinylidene fluoride resin and an inorganic filler. Further, the smoothness of at least a surface of the microporous membrane contacting the ion-exchange resin layer is 16000 seconds or less.

A three-dimensional electrode array for use in electrochemical cells, fuel cells, capacitors, supercapacitors, flow batteries, metal-air batteries and semi-solid batteries.

A mobile power supply housed within a wheeled trailer which can be towed to various locations, particularly remote locations, for providing electrical power as needed for operating equipment or for charging of batteries or other electrical supply devices at such remote locations. The apparatus includes a unique trailer design including venting means for preventing the accumulation of hydrogen normally associated with high power battery operation, particularly charging thereof and therewith, by monitoring hydrogen at all times within the trailer interior and selectively passively and actively venting the interior environment when hydrogen levels are high or whenever necessary. A unique roof design is included for gathering hydrogen near the upper portion of the interior roof construction adjacent to a venting outlet to facilitate expelling thereof.

An apparatus for manufacturing a membrane-electrode assembly for a fuel cell is provided. The apparatus includes a sub-gasket feeding unit that forms first electrode windows, unrolls a first sub-gasket sheet, and supplies the sheet to a transfer line. An electrode membrane loading unit installed over the transfer line forms electrode catalyst layers on both faces of an electrolyte membrane, collects the electrode membrane sheet cut, and loads the sheets onto first electrode windows. A sub-gasket loading unit installed over the transfer line forms second electrode windows, collects a second sub-gasket sheet, and loads the sheets on the electrode membrane sheet. MEA bonding units installed on the transfer line bond the first sub-gasket sheet, the electrode membrane sheet, and the second sub-gasket sheet mutually stacked while passing the first sub-gasket sheet, the electrode membrane sheet, and the second sub-gasket sheet between a pair of hot rollers along the transfer line.

The invention includes a reinforced membrane-seal assembly that comprises a reinforcing component, ion-conducting material, and seal material. The reinforcing component comprises a central region comprising a plurality of apertures extending from a first surface to a second surface of the reinforcing component, the central region having a first aperture area density; an inner peripheral border region surrounding the central region, where the inner peripheral border region is devoid of apertures; and an outer peripheral border region comprising a plurality of apertures extending from the first surface to the second surface of the reinforcing component, the outer peripheral border region having a second aperture area density. The outer peripheral border region surrounds the inner peripheral border region. The ion-conducting material at least partially fills each aperture in the central region of the reinforcing component and seal material fills each aperture in the outer peripheral border region of the reinforcing component.
