The protons are conducted through the membrane to the ,cathode,, but the electrons are forced to travel in an external circuit (supplying power) because the membrane is electrically insulating. On the ,cathode, catalyst, oxygen molecules react with the electrons (which have traveled through the external circuit) and protons to form water.

And conversely, at the negative electrode (also called the ,cathode,), the H + ions gain electrons to form hydrogen gas, like so: 2H + + 2e – —> H 2. These equations balance in terms of species and charges. They make the point that negative ions move to the anode and positive ions move to the ,cathode,.
