Description
Technical field
The invention belongs to hydrogen fuel cell technologies field, be specifically related to a kind of hydrogen fuel cell temperature control system.
Background technology
Hydrogen fuel cell, makes fuel with hydrogen, and oxygen makes oxidant, by the combustion reaction of fuel, is the battery of electric energy by converts chemical energy.During hydrogen oxygen fuel cell work, to hydrogen electrode supply of hydrogen, simultaneously to oxygen electrode supply oxygen.Under hydrogen, the oxygen catalyst action on electrode, generate water by electrolyte.At this moment on hydrogen electrode, unnecessary electronics is had and electronegative, owing to lacking electronics and positively charged on oxygen electrode.After connecting circuit, this course of reaction being similar to burning just can be carried out continuously.
Hydrogen fuel cell is that people solve a kind of cleaning of energy energy crisis, the new forms of energy of environmental protection; At present, hydrogen fuel cell, is also in the initial development stage, and the scope of its application and scene also have very large development space.But hydrogen is easily blasted, and ambient temperature is the key factor that set off an explosion, and therefore the monitoring of ambient temperature is for hydrogen fuel cell, extremely important.
Summary of the invention
The object of the invention is to overcome in prior art to the problem that hydrogen gas pressure controls.
For this reason, the invention provides a kind of hydrogen fuel cell temperature control system, comprise the hydrogen gas tank of hydrogen fuel cell, power cabinet, be arranged on the intelligent control circuit plate in power cabinet, be integrated in signal conversion processing circuit, single-chip microcomputer and LED that intelligent circuit board is electrically connected successively, and the temperature detection sensor to be electrically connected with signal conversion processing circuit, described temperature detection sensor is arranged in power cabinet, described LED is arranged on the cabinet door of power cabinet, is connected with single-chip microcomputer by wire; Also comprise the driving circuit for electromagnetic valve be connected with single-chip microcomputer and the electromagnetically operated valve be connected with driving circuit for electromagnetic valve; Described electromagnetically operated valve is arranged on the tank mouth of hydrogen gas tank.
The model of the drive circuit R1 resistance of above-mentioned electromagnetically operated valve is 0.5 ~ 1.5K Ω, R2 resistance to be 15 ~ 25K Ω, R3 resistance be 3 ~ 5 K Ω, Q1 is S8050.
The model of above-mentioned single-chip microcomputer is Atmel89C51, temperature detection sensor QXCPT1000.
Beneficial effect of the present invention: this hydrogen fuel cell temperature control system provided by the invention, comprise the hydrogen gas tank of hydrogen fuel cell, power cabinet, be arranged on the intelligent control circuit plate in power cabinet, be integrated in signal conversion processing circuit, single-chip microcomputer and LED that intelligent circuit board is electrically connected successively, and the temperature detection sensor to be electrically connected with signal conversion processing circuit, described temperature detection sensor is arranged in power cabinet, described LED is arranged on the cabinet door of power cabinet, is connected with single-chip microcomputer by wire, also comprise the driving circuit for electromagnetic valve be connected with single-chip microcomputer and the electromagnetically operated valve be connected with driving circuit for electromagnetic valve, described electromagnetically operated valve is arranged on the tank mouth of hydrogen gas tank, therefore, this hydrogen fuel cell temperature control system, can be good at the temperature in the power cabinet of monitoring hydrogen fuel cell, once find that the too high valve can closing hydrogen fuel cell hydrogen gas tank immediately of ambient temperature stops the use of fuel cell, and send prompting warning message by LED, until detected temperatures problem, solve, temperature has been down in the scope of fuel cell trouble free service, just again can open the valve of hydrogen gas tank, avoid hydrogen explosion occurs, improve the fail safe using hydrogen fuel cell.
