http://www.gcsescience.com/ex8.htm WebAt the anode, hydrogen is oxidized according to the reaction: producing water and releasing electrons. The electrons flow through an external circuit and return to the cathode, reducing oxygen in the reaction: producing hydroxide ions. The net reaction consumes one oxygen molecule and two hydrogen molecules in the production of two water molecules.
