Embodiment Construction

[0011] Accompanying drawing has shown structure and working embodiment of the present invention. In the picture:

[0012] 1. Activation switch; 2. On / off button; 3. Display panel; 4. Buzzer; 5. 25MPA air pressure sensor; 6. Water level sensor; 7. Voltage sensor; 8. 250MPA air pressure sensor; 9. Air intake solenoid valve ; 10, temperature sensor; 11, fan; 12, exhaust solenoid valve; 13, current sensor.

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] figure 1 The display board (3) in the middle is installed on the front panel of the power supply system, which can facilitate the operator to watch the status of voltage, temperature, water level and air pressure in real time. The switch button (2) starts the power supply system. When starting, the buzzer (4) will send an alarm sound. If the alarm continues, the operator needs to detect whether the temperature sensor (10) is connected properly, or because the volt...

Abstract

A miniature hydrogen cell stack control system is composed of a display module, an air pressure acquisition module, a voltage acquisition module, a current acquisition module, a temperature acquisition module, a liquid level acquisition module, an alarm module and an exception handling module. Data acquired by an air pressure sensor, a temperature sensor, a level sensor and a voltage sensor can be displayed at real time through a display panel. When there is an abnormal condition, the system can realize automatic protection of the electrical stack through flickering of a display panel light and alarm of a buzzer and through methods of closing loads and the like. According to the data acquired by the temperature sensor, the system adjusts revolving speed of a fan so as to make the electrical stack operate in the optimum state. Through calculating and comparing data acquired by the sensors, the control system controls related motions of an air inlet solenoid valve and an air outlet solenoid valve so as to realize automatic control of an air passage. The system can be adopted to automatically realize activation of the electrical stack, and operators can voluntarily select whether to need the activation function.

Description

technical field [0001] The utility model relates to a control system for a small hydrogen fuel cell stack. Especially the function of the fuel cell, the storage capacity of hydrogen fuel, the water level of the humidifier, the display mode of the stack voltage and temperature, and the design of the water level sensor. Background technique [0002] In the 21st century, with the continuous emergence of the problem of energy depletion, the development and use of green energy has become a hot spot of global concern, and the country is also vigorously promoting hydrogen fuel cells, because hydrogen fuel cells are a kind of power generation using hydrogen as fuel device. Its by-product is only water. It's the ideal green power option. However, a fuel cell is a device that converts chemical energy into electrical energy, and the conversion is always affected by the external environment, such as: temperature, humidity, and gas flow, which requires a control system to control thes...
