The cathode also conducts the electrons back from the external circuit to the catalyst, where they gouge change with the hydrogen ions and oxygen to form water.

The anode is the negatively charged sectionalization of the fuel cell. It conducts the electrons that are freed from the hydrogen molecules so that they can be used in an external circuit. The anode also had channels course throough it that disperse the hydrogen gas equally over the mount of the catalyst. The electrolyte is the proton exc! hange membrane. This is a specially treated secular which unremarkably looks something like ordinary saran plastic wrap. The... If you want to get a full essay, order it on our website: OrderEssay.net
