Hydrogen generator with adjustable pressure and adjusting method thereof

Abstract

The invention relates to a hydrogen generator with adjustable pressure, which comprises a switch power supply module, an electrolysis module, a gas storage device, a pressure measuring device and a control module, wherein the switch power supply module is electrically connected with the electrolysis module which is connected with a gas transmission device by a gas-guide tube, and the gas transmission device is provided with the pressure measuring device that is electrically connected with an input end of the control module; an output end of a control device is electrically connected with the switch power supply module; the pressure measuring device is used for detecting the hydrogen output pressure of the gas storage device, converting the output pressure into an electrical signal and sending the electrical signal to the control module; and the control module calculates the currently needed hydrogen production voltage, and sends a hydrogen production voltage signal to the switch power supply module which sends out corresponding electrolytic current according to the hydrogen production voltage signal. The hydrogen generator has the advantages of high control accuracy, no burnout of the electrolysis module for the protection of the self-current-limiting, convenient operation and stable electrolysis process.

Description

technical field [0001] The invention relates to a hydrogen generator, in particular to a pressure-adjustable hydrogen generator. Background technique [0002] At present, domestic hydrogen generators generally use a combination of a mechanical meter and a photocoupler, and use a light-blocking cut-off method to turn on or cut off the electrolytic current. Repeated cut-off and on-off actions lead to discontinuous electrolytic current, and the switching power supply is continuously started and overloaded, which is easy to damage the power supply and electrolytic cell. Older models use transformer rectification power supply, lack of effective over-current and over-voltage protection, and are more likely to damage the electrolytic cell due to overload. Contents of the invention [0003] The purpose of the present invention is to provide a stable and adjustable pressure-adjustable hydrogen generator for constant-current electrolysis, which has high control precision, self-limi...
