Examples
Example Embodiment
[0034] Example 1
[0035] Turn off the fuel cell stack switch, turn off the hydrogen pressure regulator (4), the hydrogen partial pressure valve (5), and turn off the hydrolysis reactor filter (12). The pressure in the hydrogen storage tank (3) continues to increase, and the water in the hydrolysis reactor (13) is continuously pressed out and enters the water storage tank (11) until the MgH in the hydrolysis reactor 2 The briquette is completely separated from the water. Close the hydrogen total pressure valve (2). Turn off the water bath circulating water pump (10). The device stops working.
Example Embodiment
[0036] Example 2
[0037] Open the hydrogen total pressure valve (2), hydrogen pressure regulator (4), hydrogen partial pressure valve (5), and open the fuel cell stack switch. Turn on the water bath circulating water pump (10). With the consumption of hydrogen, the pressure in the hydrogen storage tank (3) continuously decreases, and the water in the water storage tank (11) continuously flows back into the hydrolysis reactor (13) until the liquid level is stable. Turn on the hydrolysis reactor filter (12). The device works stably.
Example Embodiment
[0038] Example 3
[0039] In the stable operation of the device, the fuel cell is in a low power state, the hydrogen production rate exceeds the fuel cell consumption rate, the pressure in the hydrogen storage tank (3) continues to increase, and the water in the hydrolysis reactor (13) is continuously pressed out and enters the water storage. In the tank (11), until the MgH in the hydrolysis reactor 2 The briquette is completely separated from the water, and the hydrolysis reaction stops. The automatic shutdown of the hydrolysis reaction during work is realized.
[0040] With the consumption of hydrogen, the pressure in the hydrogen storage tank (3) continues to decrease, and the water in the storage tank (11) continuously flows back to the hydrolysis reactor (13), and the MgH in the hydrolysis reactor 2 When the briquettes come into contact with water, the hydrolysis reaction starts. Realize the automatic start of the hydrolysis reaction during work.
