    摘要: The present invention provides a membrane electrode assembly of a fuel cell, comprising a gas diffusion layer, a microporous layer, a catalytic layer, and an electrolyte membrane that are sequentially stacked. In the direction of an air flow path, the thickness of the microporous layer decreases progressively, the thickness of the catalytic layer increases progressively, and the total thickness of the microporous layer and the catalytic layer keeps consistent. The present application also provides a preparation method for the membrane electrode assembly of a fuel cell. The membrane electrode assembly of a fuel cell provided in the present application can balance water content of a gas inlet area and a gas outlet area of the fuel cell, and finally improves the stability of the fuel cell at different temperatures and humidity levels, thereby implementing functions such as improving the durability and decreasing a catalyst load.

    摘要: A rail transit braking energy recovery system. The rail transit braking energy recovery system comprises a braking motor, a fuel battery, an electrolytic bath, and a hydrogen tank. The braking motor is used for converting braking energy of the rail transit into electric energy. An output end of the braking motor is connected to a power input end of the electrolytic bath. The electrolytic bath comprises a hydrogen output end and an oxygen output end, the hydrogen output end is connected to the hydrogen tank, and the hydrogen tank is connected to the fuel battery and is used for supplying hydrogen to the fuel battery. In the system, only the electrolytic bath is structurally added, and the existing vehicle-mounted hydrogen tank is directly used for storing hydrogen, therefore the structure is simple, the self weight of the vehicle body is reduced, the energy conversion efficiency is high, and at the same time, the injection of hydrogen is reduced and the operation cost is reduced. In addition, the purity of the hydrogen obtained by means of electrolysis is high, so that the hydrogen can be directly supplied to the fuel battery to be used without being processed. Also provided is a hybrid power rail transit system.

    摘要: A rail vehicle lighting device includes: a plurality of short lighting fixtures (3) assembled into a long lighting fixture (4) having a shape matching with a shape of an irregular interior decoration (1). Each of the short lighting fixtures (3) is provided with a section body (5). A light source (12) is provided on the section body (5). The section body (5) is twisted such that illumination angles of included angles between each of the light source (12) and a horizontal plane are consistent. In the rail vehicle lighting device, the a plurality of short lighting fixtures (3) are assembled into the long lighting fixture (4) having the shape matching with the shape of the irregular interior decoration (1), thereby satisfying a requirement on a shape of a lighting fixture. By arranging the twisted section body (5), respective points of the long lighting fixture (4) have consistent light source illumination angles, thereby achieving a satisfactory illumination effect inside a carriage having an irregular interior decoration, and accordingly improving the appearance of the carriage.

    摘要: A central traction device for a straddling monorail train comprises a traction pin (9) and a traction beam (10). A central sleeve (22) is disposed at the center of the traction beam (10), the traction pin (9) is mounted in the central sleeve (22), the inner chamber of the central sleeve (22) is of a tightened-waist structure having bigger apertures at the upper end and the lower end and a smaller aperture at the middle part, a biconical inclined plane is formed, and an elastic rubber sleeve is disposed between the inner wall of the central sleeve (22) and the traction pin (9). The device has a simple and compact overall structure, and helps to implement connection and separation between a vehicle body and a bogie; by means of cooperation among the traction beam (10) of the tightened-waist structure, the elastic rubber sleeve and a traction rubber pile (11), transmission of traction force and braking force during operation of a vehicle in function is better implemented, the change of load in a transverse direction and a longitudinal direction as well as loading can also be better adapted, requirements of a larger traction force and a larger load change can be satisfied, and the stability and the comfort during operation of the vehicle are greatly improved.
