The system comprises the following devices: a fuel cell module, a hydrogen supply module, an oxygen supply module and a cooling module, the fuel cell module is a fuel cell system host, a KW fuel cell module is arranged in the fuel cell system host, the hydrogen supply module comprises a nozzle valve, an injection pump, a condenser, an electric pile nitrogen discharging valve and a water discharging valve, the nozzle valve is connected with the injection pump, the injection pump is connected with the condenser, the condenser is respectively connected with the electric pile nitrogen discharging valve and the water discharging valve, and the oxygen supply module comprises amixed discharging device, a throttle valve, a humidifier, an intercooler, an air compressor, an air flow meter and a filter. The hydrogen fuel cell assembly system has the advantages of being good incooling effect and the like, and solves the problems that: the efficiency of the hydrogen fuel cell becomes high, more heat is generated during work of the hydrogen fuel cell, and common cooling is difficult to meet.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a hydrogen fuel cell assembly system. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of electrolyzing water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, The electrons are released to reach the cathode through an external load, and the fuel cell is environmentally friendly. It uses electrochemical reactions instead of combustion or energy storage. The most typical traditional backup power solution, combustion will release gases such as COx, NOx, and SOx And dust and other pollutants, as mentioned above, the fuel cell will only produce water and heat, if the hydrogen is produced by renewable e...
