WlP#ad - 2. Then connect the 6v-12v dc power supply to the positive and negative wiring of the water chlorinator part, and connect the transmission line of the electric part to the electric power after 2-3 minutes, the small motor starts to work and the current is displayed on the current and voltmeter.
Positive value. Electrical part: motor with shoulder, ammeter, voltmeter. 1. 3. Pem water electrolyser proton exchange. The two proton exchange membrane electrodes in the organic base and presenter are 35mm*35mm.
Experimental steps. Add deionized water to the water level in the PEM water chlorinator. The amount of water should not be too large to prevent water from flowing into the battery. After adding water, connect the hydrogen gas outlet on the water electrolyzer to the hydrogen gas inlet on the electric power with a gas pipe. 4. Ammonia fuel cell.
