Abstract
The invention relates to a hydrogen oxygen fuel cell panel type teaching aid, which consists of a Y-shaped tee (1), a catheter (2) with a piston, a porous carbon rod (3), a latex tube (4), an ordinary funnel (5), a sensitive current meter (6), a musical greeting card (7), a diode (8), a buzzer (9), a direct-current power supply (10) and a multi-direction switch (11), and is characterized in that when the multi-direction switch (11) is opened, a pointer of the sensitive current meter (6) spins, light is emitted by the diode, and sound is uttered by the buzzer (9). According to the structure of teaching aid saturated Na2SO4 solution is electrolyzed by the 16V direct-current power supply, only about 3 minutes is needed to store gas for a fuel cell experiment. When the teaching aid is used by a teacher in class teaching, the process of erecting an experimental device can be eliminated, time can be saved, and the whole class can clearly observe experimental phenomena.
Description
Technical field
The present invention relates to first, senior chemistry classroom experiment teaching aid, help the composition of students ' understanding water, the perception hydrogen-oxygen fuel cell, understand the application of the principles of chemistry in the energy and high and new technology field.
Background technology
Brine electrolysis and hydrogen-oxygen fuel cell be just, senior chemistry course chemical energy and the electric energy important content in mutually transforming.It is green energy resource that teaching material first allows the student understand Hydrogen Energy at Junior, and the Conversion of Energy mode while understanding chemical cell (comprising fuel cell) electric discharge, for the principle of work of further learning fuel cell to senior high school period lays the foundation.
Known a kind of hydrogen-oxygen fuel cell panel formula teaching aid is to fill saturated Na
2SO
4In the small beaker of solution, insert Y tube, and mix graphite electrode at the Y tube two ends, by electrolysis by H
2And O
2Be stored in respectively the Y tube two ends, then observe the LED lighting situation with wire connection two ends graphite electrode and light emitting diode, energising.After test, find: Y tube can complete the fuel cell experiment, and volume is little, the material-saving that saves time, and can separate gaseous product is ingenious, still, there are problems in the microminiaturization of this device.For example: (1) because the Y tube volume is little, the gas flow that can store is limited, and generation current intensity is little, can only detect with sensitive galvanometer, and the luminescence phenomenon of light emitting diode is not obvious, is not easy to observe.(2) bore due to Y tube is little, is difficult to find the rubber stopper of coupling.By after the pencil skiving, exposing one section pencil-lead, test as electrode, but difficulty has appearred in the sealing of the mouth of pipe.(3) high to the device sealing requirements to the operation of filling electrolytic solution in Y tube, and complicated operation, difficulty, electrolytic solution also can be stained with to hand.(4) there is no fixedly Y tube of suitable clamping instrument, during experiment, Y tube can only be placed in beaker, install lack of standardization.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of hydrogen-oxygen fuel cell panel formula teaching aid, be material, the size of electrode surface area, generation H from electrode
2And O
2How many equal angles of amount have been launched further test, to obtain larger strength of current.
Technical scheme of the present invention is achieved in the following ways: a kind of hydrogen-oxygen fuel cell panel formula teaching aid, by breeches pipe, conduit with piston, the porous carbon-point, emulsion tube, common funnel, sensitive galvanometer, music greeting card, diode, hummer, direct supply and multi-direction switch form, with wire respectively by porous carbon-point and the music greeting card at breeches pipe two ends, sensitive galvanometer is connected, with the conduit of piston, be inserted in respectively two ends of breeches pipe, common funnel is connected to the lower end of breeches pipe by emulsion tube, multi-direction switch is controlled the switching of direct supply, it is characterized in that: described multi-direction switch is opened, the sensitive galvanometer needle deflection, LED lighting, the hummer ring.
Described porous carbon-point 3 is the thick diameter multi-hole carbon-point of diameter 1.5cm.
Described breeches pipe 1 is at one section glass arm of U-shaped pipe bottom sintering, forms breeches pipe.
Structure of the present invention, adopt the saturated Na of 16V direct supply electrolysis
2SO
4Solution, only need electrolysis 3min left and right, and the gas flow of storage can complete the fuel cell experiment.The teacher uses this teaching aid at classroom teaching, can save the process of building experimental provision, saves time, and can allow again the full student of class observe clearly experimental phenomena.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of hydrogen-oxygen fuel cell panel formula teaching aid, by breeches pipe 1, conduit 2 with piston, porous carbon-point 3, emulsion tube 4, common funnel 5, sensitive galvanometer 6, music greeting card 7, diode 8, hummer 9, direct supply 10 and multi-direction switch 11 form, with wire respectively by the porous carbon-point at breeches pipe 1 two ends 3 and music greeting card 7, sensitive galvanometer 6 is connected, with the conduit 2 of piston, be inserted in respectively two ends of breeches pipe 1, common funnel 5 is connected to the lower end of breeches pipe 1 by emulsion tube 4, multi-direction switch 11 is controlled energising or the outage of direct supply 10, described multi-direction switch is opened, sensitive galvanometer 6 needle deflection, diode 8 is luminous, hummer 9 rings.Porous carbon-point 3 is the thick diameter multi-hole carbon-point of diameter 1.5cm.Breeches pipe 1 is at one section glass arm of U-shaped pipe bottom sintering, forms breeches pipe.
The present invention, repeatedly after teaching practice, find: the effect of be applied to just, high school chemical experiment being imparted knowledge to students is obvious.It can merge " chemical experiment " and " application of principle " mutually, makes that the student is with keen interest to experimental phenomena, enthusiasm is surging, and experimental principle is full of and probes into wish, vivider, firm to mastery of knowledge.Simultaneously can also allow students experience to chemical science, serve the practicality of human social development.
