Minson oxyhydrogen fuel cell new energy application demonstration car science inquiry teaching experiment instrument

Fuel cell principle ​         The fuel cell is composed of an anode, a cathode and an ion-conducting electrolyte. Its working principle is similar to that of a common electrochemical cell. The fuel is anodized, the oxidant is reduced at the cathode, and electrons flow from the anode to the cathode through an electric load circuit to generate an electric current.         The product consists of a transparent plastic trolley, a fuel cell (electrolytic, power generation), a 2:1 capacity hydrogen and oxygen storage tank and supporting battery box and electrical appliances.         During the experiment, open the silicone plug in the middle of the gas tank, use the plastic syringe to inject distilled water or purified water into the lower part of the gas storage tank to the water line, and then plug the middle waist; unplug the banana plug wire connected to the fuel cell. Take the 1.5V 5th battery and put it in the battery box. Connect the battery box and the battery with two bananas. (Note that the positive and negative electrodes are not connected, otherwise the gas generated by the electrolysis corresponds to the error, which not only affects the experiment. The effect, and will cause damage to the fuel cell. When electrolysis, please do not leave the product, because the electrolysis process can reach the gas in the gas storage tank to the top of the tank in 2 to 3 minutes. At this time, unplug it. Connect the battery to the fuel cell, connect the banana plug of the car to the fuel cell, and then select the third switch at the rear of the car to see the LED light, the trolley walking, and stop.         The fuel cell emits electricity at around 0,8V, which can be used to drive the car over the ground for more than 10M until the hydrogen and oxygen are exhausted.
