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 method, device and system for controlling air supply of fuel cell, and a railway vehicle are disclosed. The method includes: continuously inputting reaction air to a fuel cell based on a preset excess coefficient, wherein the preset excess coefficient is greater than a standard excess coefficient; in a case that a working power of a target object is increased, detecting whether a current excess coefficient is less than or equal to the standard excess coefficient in real time or regularly; and if it is detected that the excess coefficient is less than or equal to the standard excess coefficient, increasing the current excess coefficient to the preset excess coefficient. The disclosure solves the technical problem that the existing fuel cell is relatively slow in response when the electricity consumption demand is increased.

摘要： A method, device and system for controlling a fuel cell and a rail vehicle are provided. The method includes: an operating power of a target object is detected, wherein the target object is powered by at least two fuel cells (S102); when it is detected that the operating power of the target object is lower than a predetermined power, at least one fuel cell is turned off or a cell component in any one or more fuel cells is turned off according to a gas conversion range corresponding to the fuel cell (S104), wherein the gas conversion range is an output power range value, of the fuel cell, corresponding to a preset range value of a hydrogen conversion rate of the fuel cell. The method solves a technical problem in the related art of low hydrogen conversion rate of the fuel cell in the case of low power of an electrical appliance caused by the fact that the automatic control cannot be implemented on a plurality of fuel cells according to the operating power of the electrical appliance.
