Abstract: 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.

Abstract: 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.

Abstract: The present invention provides a microporous layer structure of a fuel cell, comprising: a microporous layer having high water vapor transmission rate and a microporous layer having low water vapor transmission rate that are sequentially stacked. In the direction of an air flow path, the thickness of the microporous layer having high water vapor transmission rate increases progressively, the thickness of the microporous layer having low water vapor transmission rate decreases progressively, and the total thickness of the microporous layer structure keeps consistent. At an air inlet, the thickness of the microporous layer having high water vapor transmission rate is smaller than that of the microporous layer having low water vapor transmission rate. At an air outlet, the thickness of the microporous layer having high water vapor transmission rate is greater than that of the microporous layer having low water vapor transmission rate.
