Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1-4 shown.

[0023] A fuel cell backup power system based on communication, which includes a hydrogen supply unit, a fuel cell unit, a DC / DC unit, an output unit, a patrol unit, an analog acquisition unit, a main control unit and a human-computer interaction unit;

[0024]The hydrogen supply unit includes a reforming unit, a purification unit and a hydrogen storage bottle. The reforming unit uses hydrocarbon water vapor reforming reaction or incomplete oxidation reaction to prepare hydrogen. After passing through the purification unit, hydrogen with a purity of >99.9% is obtained and stored in the hydrogen storage tank. Reserved in the bottle; the prepared hydrogen is decompressed by the pressure reducing valve and then sent to the fuel cell unit; the fuel cell unit is used to burn hydrogen to generate DC power and heat, and the ...

Abstract

The invention relates to a backup power system for a fuel cell for communication. The backup power system comprises a hydrogen-donating unit, a fuel cell unit, a DC / DC (Direct-current / Direct-current) unit, an output unit, a patrolling unit, an analog acquisition unit, a main control unit and a human-computer interaction unit. The hydrogen-donating unit realizes the aim of preparing high-purity hydrogen through carbureted hydrogen; the fuel cell unit is used for converting chemical energy into direct-current electric power; the DC / DC unit is used for adjusting output voltage of the fuel cell so as to supply power to the output unit; the output unit is used for supplying power to a communication base station after city electricity is powered down; the patrolling unit is used for acquiring voltage of a monocell; the analog acquisition unit is used for acquiring various data signals in the system and transmitting the data signals to the main control unit; the main control unit is used for analyzing data and sending a control signal to each unit; and the human-computer interaction unit is used for completing the functions of short-range communication, remote communication, monitoring, alarming and the like. The system is high efficient, clean, safe and reliable, has high intelligence, can realize seamless connection with city electricity supply when being used as a communication standby power supply, and simultaneously, does not need to be charged, and can be continuously operated for a long time.

Description

technical field [0001] The invention relates to a fuel cell system, in particular to a communication fuel cell backup power supply system. Background technique [0002] As we all know, fuel cells can directly convert the electrochemical energy of fuel into electrical energy. Since they are not limited by the Carnot cycle, their efficiency is as high as 60% to 80%, which is much higher than that of internal combustion engines. At the same time, when fuel cells use hydrogen as fuel, The product is only water, which is clean and has no pollution to the environment; because of the electrochemical reaction inside it, there is no noise pollution. A fuel cell is a power generation device, which is different from batteries such as lead-acid that need to be charged. As long as hydrogen is supplied, electricity can be continuously obtained. Fuel cell power supplies are widely used in communications, finance, hospitals, schools, commerce, industrial and mining enterprises and resident...
