Embodiment 1
[0058] An embodiment of the present invention discloses an offline stack activation system for fuel cells, such as figure 1 As shown, a humidification activation device and a controller are included.
[0059] The humidification and activation device includes an integrated high-pressure gas storage device without hydrogen, a flow control valve, a humidifier, and a gas circulation pump, and is provided with an installation slot for placing the stack to be activated. At least one gas inlet of the stack to be activated on the installation slot is connected to the outlet of the high-pressure gas storage device through a humidifier and a flow control valve in sequence, and the other is connected to the gas outlet corresponding to the gas inlet of the activated stack through a gas circulation pump.
[0060] The controller is used to select the matching gas inlet of the to-be-activated stack according to the gas type in the high-voltage gas storage device to conduct after the stack to...
Embodiment 2
[0064] Improvement is made on the basis of Example 1, and the humidification and activation device also includes a heating cable.
[0065] Wherein, the heat tracing belt is arranged on the connecting pipeline between the gas outlet of the humidifier and the gas inlet of the stack to be activated, and the control end is connected to the output end of the controller, and is used for setting a suitable heat tracing temperature, So that the gas in the pipeline of the layout section is not condensed.
[0066] Preferably, the humidification and activation device further includes a gas-water separator.
[0067] Wherein, the hydrogen tail gas outlet and the air tail gas outlet of the stack to be activated on the installation groove of the humidification activation device are connected in parallel with the input end of the gas-water separator.
[0068] The gas-water separator is used to feed back the liquid to the humidifier for recycling after the output gas of the stack to be activa...
