But this does not prevent it from becoming an excellent fuel cell component. First, it is in the battery, so people don't have to worry about touching methanol. Let's make an inappropriate analogy, just like you won't get an electric shock when you call your mobile phone (unless your mobile phone is broken:)
Methanol oxidation produces high energy, and the products are only water and carbon dioxide. Compared with other common petroleum energy sources, it can be said to be clean, and the products are non-toxic and pollution-free. Compared with batteries, it contains no heavy metals. Even if you insist that methanol will poison people, it may bring much less than batteries.
In addition, a small amount of methanol is harmless to human body. Methanol is mainly absorbed through the respiratory tract and digestive tract, and only a small amount is absorbed by the skin.
In case of methanol poisoning, after gastric lavage, oral administration or injection of ethanol can detoxify.
