Note: 1， how to make a brine solution: add salt， water in a (salt) to 5 (water). Any proportion of the salt from 20% to 99% of water is possible， but20% is the most effective. 2， after a period of use brine， cars will increasingly slow and then stop. Then add salt can start the car again. 3， each piece is a consumable anode metal may be oxidized， can not be used if it is eroded， you can replace it with a new anode metalsheet (product suite contains two anode metal sheet). 4 If the brine does not require a long time to drive the car， do not use it， need to clean FC module: Rinse the cathode plate， remove the anode plate residual salts were drying all parts， otherwise it will shorten the life of the anode metal sheet. Anode plate was washed off with water after each use and that the surface of the etched layer， if more than 10 times per day， said anode plate 20 can be a few days， if the second time with 1 to 2 months can be used， which is about 60 to about 70 times
