A self-regulating hydrogen generator for a hydrogen fuel cell. The apparatus comprises the following components: a fuel tank with a definable internal volume with a rated volume, the fuel tank being equipped with a hydrogen discharge opening communicating with the internal space, a catalyst containing hydrogen storage material and stored in the fuel tank, wherein the catalyst is filled in In the catalytic reactor, the reactor is equipped with a closing part which can be used to block the contact between the catalyst and the fuel liquid and the opening part in contact with the fuel liquid, so that it can be actively adjusted according to the rise and fall of the pressure in the fuel tank. Hydrogen or suspend hydrogen generation.

Instrument installation and use
(a) Preparation before starting:
a. Take out the instrument from the packing box, check whether there is any damage caused by improper transportation, check whether the spare parts, certificate and warranty card are complete.
b. Add electrolyte: Take out the potassium hydroxide from the spare part and pour it into a container. Then add 500ml of distilled water or deionized water as mother liquor. Stir the electrolyte completely until it is completely cooled.
c. Open the reservoir cover and remove the inner cover. (The inner cover is used to prevent liquid leakage during transportation. Do not run it with the inner cover when it is used. Please be sure to keep the inner cover so that it can be used again for transportation.)
d. Pour the cooled electrolyte (mother liquor) into the reservoir, then add distilled water or deionized water. Do not exceed the upper limit water line, and do not go below the lower limit water line. Screw on the outer cover.
(b) Self-test of the instrument: (Do not connect with the chromatograph)
a. Turn on the power.
b. Turn on the power switch. At this point, the instrument pressure gauge starts to rise. Check whether the electrolysis indicator (green light) on the instrument panel is illuminated. The digital flow display (digital display) should be greater than 300 (500) and less than 350 (550). Within 6 minutes, the pressure indication (pressure gauge) should reach 4Kg/cm2 (about 0.4MPa), and the digital flow display should be reduced to "000", indicating that the instrument system is working properly and the self-test is qualified.
(C) the use of the instrument:
a. Remove the seal nut on the air outlet on the back of the instrument (please save it for future self-test instruments). Use an outer diameter Φ3 gas line tube to connect the outlet of the self-tested hydrogen generator with the hydrogen inlet of the chromatograph. Tighten the nut and the seal must be good. Turn on the power switch and the instrument enters the working state.
b. When the instrument is used, it should be noted whether the flow rate display is consistent with the amount of gas used by the chromatograph. If the flow rate exceeds the actual amount of the chromatograph, it should be shut down for leak detection. Please refer to Figure 2 of the method of the instrument for troubleshooting reasons and exclusion methods, and then use the self-test method before passing inspection.
c. The instrument can select two gears according to different outlet pressures required by the user. When using hydrogen as a carrier gas (for example, TCD), set the pressure to H in order to obtain a stable flow rate and sufficient pressure, and set the pressure to L when using hydrogen as a fuel gas (such as FID). In order to extend the life of the electrolytic cell. The pressure setting switch is inside the instrument, and the instrument shell is opened. A toggle switch can be seen beside the pressure controller between the two filters. The user can adjust H and L in two gears according to different use requirements. H is 6 Kg/cm2 (about 0.6 MPa), L is 4 Kg/cm2 (about 0.4 MPa), and the pressure of the instrument is set at the L position.
d. The instrument is equipped with two filters. The stage filter is equipped with color-changing silica gel, and the second-stage filter is equipped with a molecular sieve. During the use, check whether the silicone in the filter is discolored through the observation window. If it is discolored, replace it immediately or regenerate it. The method is: unscrew the filter, and then unscrew the filter cover, replace the silicone, tighten the filter cover, screw the filter to the base, and check for leaks.
e. Suggestion: Change the color change silica gel three times and replace the molecular sieve once.
f. After the instrument is used for a period of time, the electrolyte will gradually decrease and the electrolyte level will approach
Timely replenishment should be done in a timely manner. Only double distilled water or deionized water can be added at this time. Do not exceed the upper limit water level when adding liquid. (The concentration of potassium hydroxide used in the hydrogen generator is about 10%)
g. Do not operate the instrument at no load for a long time when the pressure is "0". The electrolytic cell and the switching power supply components will be burned out during no-load operation. Causes damage to the entire instrument.
h. The user should not disassemble and open the electrolytic cell (the user cannot repair it by himself) so as not to affect the operation of the whole machine.
i. When the instrument needs to be transported, clean the electrolyte in the reservoir with a syringe.
Note: The electrolysis cell of this instrument is in the form of a barrel. There is a considerable portion of the electrolyte in the electrolysis cell. Therefore, after the electrolyte in the reservoir is sucked, the instrument is to be tilted backward by 90°. At this time, electrolysis in the electrolysis cell is performed. The liquid will flow into the reservoir, and then use the ear wash ball to suck the electrolyte in the reservoir. After the inner cover is fitted, the cover is screwed on to prevent the residual electrolyte from spilling during transportation, and the entire instrument will be irreparably corroded.
